The Royal Gourmet GA6402S delivers 74,000 total BTUs from five main burners plus a dedicated 14,000 BTU sear burner, making it the highest raw heat output in this lineup. The sear burner sits between the main cooking zone and the side burner, giving you a concentrated infrared-like zone for charring steaks without heating the entire grate surface. With 835 square inches of total cooking space, it can hold 21 burgers simultaneously, which is practical for a crowd of eight to ten.

Flame tamers sit above each burner to distribute heat and vaporize drippings, while the removable grease tray and cup keep cleanup under control. Porcelain-enameled cast iron cooking grates retain heat well, though the grates are on the lighter side compared to premium cabinet models. The six-burner layout allows for flexible zone cooking—turn off a center burner and use indirect heat for bone-in chicken or pork shoulders.

Assembly requires a couple of hours with two people due to the cabinet frame and the number of components. The alloy steel frame is powder-coated rather than fully stainless, so keeping it covered when not in use extends its lifespan significantly. For anyone hosting regular backyard parties and wanting a burner count that impresses without a four-figure price tag, this grill earns its spot near the top of the list.

The Weber Genesis E-325 represents the gold standard for mid-to-premium freestanding grills. It uses three PureBlu burners with a tapered design that produces a consistent flame across the entire cooking surface—no hot-and-cold spots even after an hour of grilling. The extra-large sear zone concentrates heat on one side of the 641-square-inch total area, so you can seat multiple steaks simultaneously while cooking delicate fish or vegetables on the cooler side.

Porcelain-enameled cast-iron grates sit above Weber’s FLAVORIZER bars, which catch and vaporize dripping juices to create smoke flavor while funneling excess grease away from the burners. The grease management system uses a pull-out tray that slides out from under the cookbox, making disposal a clean, two-second operation. The warming rack keeps toasted buns or finished meat warm while the rest of the meal finishes cooking below.

Side tables are spacious enough for a platter and a sauce bottle, but there is no built-in side burner—that is an add-on through the Weber Crafted accessory system. The painted steel cabinet is durable, but the cast-iron frame gives it a heavy, stable feel during use. For cooks who prioritize even heat distribution, flare-up control, and brand-backed durability over burner count, this is the most well-rounded option in the category.

The Monument Grills 4+2 configuration packs four 304 stainless steel main burners plus a dedicated side burner and a high-heat infrared sear burner into a 723-square-inch package. The side burner is ideal for heating sauces or sides, while the sear burner cranks out intense heat for a quick crust on steaks without firing up the entire main grate. This makes it a strong choice for cooks who want multi-zone capability without stepping up to a six-burner footprint.

Porcelain-coated cast iron grates sit above stainless steel flame tamers that distribute heat and vaporize drippings. The ClearView window in the lid allows you to check food without lifting the lid and losing heat, and the built-in knob lights make nighttime grilling easier. The brushed stainless steel finish on the cabinet resists fingerprints and weather better than painted steel, though the cart-style frame is still relatively lightweight compared to built-in units.

Assembly is moderate—the instructions are clear, but handling the stainless panels requires care to avoid scratches. The warming rack adds 190 square inches of secondary space, which is generous for a 4+2 layout. For backyard cooks who regularly grill for a family of six and want the flexibility of a sear station and a side burner in one unit, this Monument delivers a strong value proposition.

The Spire 6 Burner Built-In grill is designed for permanent outdoor kitchen islands. With six 10,000 BTU burners plus a rear burner for rotisserie cooking, the total heat output hits 73,000 BTUs across 904 square inches of cooking space—the largest surface area in this review. The rear burner is a game-changer for cooks who want to slow-roast a whole chicken or prime rib on a rotisserie spit while using the main grates for sides.

All cooking grates are constructed from 304 stainless steel, which provides excellent corrosion resistance and easy cleaning compared to cast iron. The burner system is designed for dual-fuel compatibility, so you can run it on propane or convert to natural gas using a conversion kit. Interior lights illuminate the cooking chamber, which is helpful when checking doneness at night without lifting the heavy stainless lid.

This is a built-in unit, meaning it requires a cutout in an outdoor kitchen island or a compatible enclosure—it is not freestanding. The polished stainless steel finish looks modern and resists rust, but it will show fingerprints and water spots in humid climates. For homeowners building a dedicated outdoor kitchen and wanting a high-BTU, large-capacity built-in with rotisserie functionality, this Spire model is a serious contender.

The Char-Broil Pro Series uses Amplifire infrared technology, which diffuses heat across a metal plate instead of direct flame contact. This design eliminates flare-ups almost entirely—grease drippings vaporize on the hot plate rather than igniting—and it heats up to 500°F in under ten minutes. With 535 square inches of primary cooking space plus a 155-square-inch warming rack, the total cooking area sits at 802 square inches, but the lower 45,000 BTU output means the heat is evenly dispersed rather than concentrated.

The standout feature is the modular cooking system. The heavy-duty cold-rolled steel griddle surface (328 square inches) drops into place over the grates in under 90 seconds, letting you switch from grilling burgers to cooking pancakes without a separate appliance. You can also add patented Gas2Coal charcoal trays (sold separately) to run charcoal on the same grill body—though this requires removing the infrared plates first.

The oversized side shelf provides ample workspace, and the two 8-inch wheels plus locking casters make rolling across uneven patio surfaces manageable. The porcelain-coated cast-iron grates resist rust but require careful handling. For the cook who wants one appliance that can grill, griddle, and even run charcoal on occasion, this Char-Broil offers versatility that no other single grill in this list can match.

The Monument Grills 4-Burner Convertible is engineered for flexibility. It ships ready for propane, but the inclusion of a separate conversion kit (model 97352) allows you to switch to natural gas without buying a second grill. This is a critical feature for homeowners who already have a natural gas line on their patio and want to avoid the recurring expense of propane tank refills. Four 304 stainless steel main burners plus a side burner produce 60,000 total BTUs across 723 square inches of cooking area.

Porcelain-coated enamel cast iron grates are easy to clean and resist chipping better than uncoated cast iron. The ClearView lid lets you monitor cooking progress without lifting, and the advanced temperature control system allows precise flame adjustments for delicate foods like fish or vegetables. The brushed stainless steel finish on the cabinet keeps fingerprints at bay better than polished stainless.

The unit ships in two packages—the grill body and the conversion kit—and they may arrive on different days, so plan ahead if you need the conversion kit right away. The freestanding cabinet is stable on flat surfaces, but the lack of a dedicated sear burner means you will not get the same intense heat concentration as the 4+2 Monument model. For anyone planning a long-term patio setup who wants to avoid propane logistics, this convertible design is a smart investment.

The Kenmore 3-Burner grill is a compact solution for small patios, balconies, or anyone who needs to collapse and store their grill between uses. When the side tables are folded down, the grill measures just 32.5 inches wide—nearly half its 51-inch extended width. This folding mechanism does not require tools; you simply lift the tables into position or drop them for storage. The 381-square-inch primary cooking area combined with a 131-square-inch warming rack gives you enough room to grill up to 20 burgers at once, which is impressive for the footprint.

Cast-iron cooking grates with a porcelain coating provide good heat retention for even cooking. The 1-button electronic ignition lights reliably on the first press, and the built-in lid thermometer gives real-time temperature feedback. Four caster wheels (two lockable) make it easy to roll across grass or concrete and lock into position on uneven surfaces.

The 30,000 BTU total output is on the lower end of this lineup, which means preheating takes longer and the grill may struggle to maintain high heat in windy conditions. The powder-coated finish on the alloy steel frame is durable but not as corrosion-resistant as stainless steel. For renters, apartment dwellers, or anyone who needs a portable grill that folds down for closet storage, this Kenmore delivers a solid grilling experience without demanding permanent patio real estate.

The Spire 5 Burner Built-In grill is a slightly smaller sibling to the 6-burner version, with 63,000 BTUs from five 10,000 BTU burners plus a 13,000 BTU rear burner for rotisserie cooking. The 750-square-inch total cooking area is still generous for a built-in unit, and the polished stainless steel frame with 304 stainless grates provides long-term corrosion resistance. Rear burner output at 13,000 BTUs is slightly higher than the 6-burner model’s, making rotisserie chicken and prime rib a realistic weeknight option.

The dual-fuel compatibility means it can run on propane or natural gas with a conversion kit. The interior lights are bright enough to see food clearly at night without opening the lid. Customer feedback highlights that the built-in design requires an insulated grill jacket if installed in a combustible enclosure—this is a critical detail for anyone planning new construction or a remodel with a grill cutout.

At 34 inches wide, this unit fits standard outdoor kitchen cutouts and leaves room for side burners or storage drawers in the island. The 304 stainless steel grates are lighter than cast iron but never rust and are simple to scrape clean after each use. For homeowners building a mid-sized outdoor kitchen who want a rear rotisserie burner and a polished stainless aesthetic without stepping up to the full 6-burner, this Spire strikes a functional balance.

The Megamaster 5-Burner is an entry-level grill that offers a lot of square footage for the investment. With 50,000 BTUs across five 10,000 BTU burners and 656 square inches of cooking space, it provides a generous cooking area for family dinners and smaller gatherings. The stainless steel burners heat up quickly, and the matte-finish cast iron cooking grates offer good heat retention and a non-stick surface that improves with seasoning over time.

The porcelain-coated steel firebox is lighter than full stainless or cast-iron fireboxes, which makes the grill easier to move around the patio using the two-wheel transport system. Two large side prep tables fold down when not in use, and accessory hooks on the sides keep tools within reach. The painted finish on the frame saves weight and cost, but it is less resistant to weather than powder-coated or stainless finishes.

This grill is designed for the price-conscious buyer who wants a five-burner format without paying for a stainless cabinet. The painted finish and lighter firebox mean it will show wear faster if left uncovered in rain or snow. The heating power produces adequate heat for most backyard cooking, but the BTU-per-square-inch ratio sits around 76, which is on the lower end for serious searing. For entry-level cooks or occasional grillers who want a large surface area at a low entry point, the Megamaster delivers the basics without frills.
