Weber Spirit II E-310 vs Napoleon Prestige 500: What Backyard Grillers Actually Say

The Napoleon Prestige 500 runs a combined 66,000 BTU across its main burners plus a separate 18,000 BTU infrared rear burner, and owners notice it: one wrote that they can hit 700 degrees on the main grill using just the four burners, without touching the infrared section. That headroom is what owners cite when they talk about steakhouse-style sear marks, and Napoleon's Even Cooking subscore (9.0/10) backs up that the extra heat isn't coming at the cost of hot spots. Its porcelain-coated cast-iron WAVE grates are called out specifically for producing consistent grill marks and holding heat well for searing. The Weber Spirit II E-310 runs fewer, lower-output burners and posts an 8.5/10 Cook Performance subscore rather than a top-tier one — consistent with an owner who said searing steaks isn't quite as good as "their top end" but is satisfactory for regular use. Weber's own flavorizer bars get credit in its pros for adding smoky depth by vaporizing drippings, which owners describe as a meaningful flavor difference over a plain gas grill. Neither product's owner sample describes uneven cooking or cold spots; the difference reported is ceiling, not consistency.

The Napoleon's 12 owner mentions split 6 positive, 3 mixed, and 3 negative, and a real pattern runs through the mixed and negative ones: two separate posts describe the side burner never lighting from its igniter, a third negative post describes the rear burner's igniter barely sparking, and a fourth negative post describes the infrared rear burner producing normal flame instead of actual infrared heat. A fifth negative mention flags stripped screw threads during assembly. That's roughly a third of the Napoleon sample touching ignition, infrared function, or assembly quality — a repeated enough pattern to take seriously if you're weighing the rotisserie feature specifically. Napoleon's Canadian Build Quality subscore is still high (9.5/10), and its Warranty subscore (9.0/10) reflects the lifetime coverage on burners and grates, but the ignition cluster is worth reading before buying. The Weber Spirit II E-310's sample is thinner at 5 mentions, but all 5 are positive, and its Durability & Build Quality subscore (9.5/10) is the highest subscore either grill carries in this pack. Weber's pros also cite its Infinity ignition system lighting every burner instantly without repeated clicking, which lines up with the absence of any ignition complaints in its (smaller) mention sample.

At roughly $799 CAD for the Weber against roughly $1,299 CAD for the Napoleon, the gap is about $500 — narrower than the $600 the older version of this page cited, based on the current pack pricing. Weber's Value subscore (8.5/10) edges out Napoleon's (8.0/10), and Weber's own product notes flag that it costs more than similarly specced budget grills but wins on long-term durability. Napoleon's product notes carry their own value caveat: the rotisserie motor and spit rod that unlock the infrared burner's signature use case are sold separately and not included in the $1,299 price, so buyers who want that feature should budget past the sticker price. Napoleon's high fuel draw is another line item worth planning for — with 66,000 main, 10,000 side, and 18,000 rear BTU available, a 20 lb propane tank runs through fewer full sessions than it would on a lower-output grill, so frequent users are better off keeping a spare tank on hand.
