The Weber Spirit II E-310 is the best-selling gas grill in America and it earns that position. The GS4 high-performance grilling system delivers even heat across the entire grate, the porcelain-enameled grates retain heat and clean easily, and Weber's 10-year warranty covers everything that matters. The benchmark 3-burner grill.

Napoleon's Prestige 500 is the full-featured premium grill. The infrared SIZZLE ZONE burner hits 1800°F for restaurant-quality sear marks, the 4 main burners plus rear rotisserie burner cover every cooking technique, and the premium stainless construction is built to last decades. The right choice for serious outdoor cooks.

The Char-Broil Performance 4-burner is the budget grill that gets the job done. The 4 stainless steel burners provide 32,000 BTU total output over 425 square inches of primary cooking space. For occasional weekend grilling where you don't want to invest $600+, Char-Broil is a practical choice.

Broil King builds grills that last longer and cook hotter than the competition at the same price point. The Flav-R-Wave system maximizes heat from every BTU, the dual-tube burners are virtually indestructible, and the 690 square inches of total cooking space is enormous. Weber's main rival for value in the $700-900 category.

The Genesis EX-335 brings Weber's best grilling performance together with their Weber Connect smart hub. Built-in temperature probes monitor your food and send phone alerts when to flip or pull. The Genesis grilling system is Weber's best heat distribution technology. For tech-forward cooks who want connected grilling.
Marketing BTU numbers (40,000 BTU, 60,000 BTU) are poor indicators of actual grilling temperature. What matters is BTU per square inch of cooking area. A grill with 40,000 BTU and 400 sq inches cooks hotter than one with 60,000 BTU and 800 sq inches. Weber's GS4 system with 30,000 BTU is hotter than cheap grills with 50,000 BTU because of superior heat management.
Cast iron grates retain heat best and create the clearest sear marks — but require seasoning and rust if not maintained. Porcelain-coated cast iron (Weber) gives you cast iron's heat retention with rust resistance and easy cleaning. Stainless steel grates are the most durable and low-maintenance but don't retain heat as well as cast iron.
Weber's 10-year warranty (burners/cooking grates) is a signal of build quality confidence. Manufacturers who won't stand behind their grill for 10 years are telling you something. Budget grills with 1-year warranties are priced to be replaced, not repaired.
Both are excellent; the choice depends on price and features. Weber's Spirit and Genesis lines are the benchmark for reliable everyday grilling. Napoleon's Prestige and Rogue lines add infrared sear burners and premium stainless at higher prices. For most backyard cooks, Weber's quality is sufficient. Serious outdoor chefs who want restaurant-level searing should consider Napoleon.
For a typical 3-4 burner grill with 400-500 sq inches of cooking space, 30,000-40,000 BTU is adequate. The BTU number matters less than heat distribution — a well-designed 30,000 BTU grill cooks better than a poorly designed 60,000 BTU grill.
