Napoleon's Prestige 500 RSIB is the steakhouse weapon in this lineup. The 1,000°F ceramic infrared side burner sears thick ribeyes the way a Weber simply can't, the 18,000 BTU rear rotisserie burner spins whole chickens to crisp-skinned perfection, and AmazingRibs gave it their full Platinum Medal at 5/5. Built from 304 stainless steel with a lifetime cookbox warranty, the Prestige 500 is the grill for hosts who care about searing and rotisserie cooking. It's not the easiest to assemble and the warming rack is fragile, but the cooking-feature set at this price has no real competitor.

Sear and Temperature Range
The Prestige 500's signature feature is the 14,000 BTU SIZZLE ZONE ceramic infrared side burner. AmazingRibs measured it 'gets over 1000°F and sears two steaks beautifully' — temperatures that turn a one-and-a-half-inch ribeye into a steakhouse-quality crusted slab in about 90 seconds per side. No Weber under $4,000 sears at that temperature. Add the 18,000 BTU infrared rear rotisserie burner and you can spit-roast a whole chicken under direct radiant heat while finishing sides on the four main burners. The four main 12,000 BTU PureBlu burners hold 600°F on high for conventional grilling and drop cleanly to 250°F for indirect chicken thighs. Range and ceiling both exceed every Weber in this comparison.
The ceramic infrared burner is the real engineering story. Conventional gas burners heat air, which then heats food via convection — efficient at moderate temperatures, lousy at searing because hot air doesn't transfer energy fast enough to outpace moisture loss. Infrared radiates energy directly at the food surface, so the crust forms in seconds before the interior overcooks. The Prestige 500's ceramic plate is honeycombed with hundreds of small flame holes that produce uniform radiant heat across the burner area. That's the same mechanism a $5,000 Lynx commercial grill uses, ported into a $1,500 package. For thick steaks, the difference versus a conventional sear zone is dramatic.
Build Quality and Materials
Napoleon constructs the Prestige 500 from solid 304 stainless steel — the same grade you'd find on a $5,000+ Lynx or DCS grill. AmazingRibs praised the construction in their Platinum Medal review: high-quality 304 stainless for long-term durability, 9.5mm-thick WAVE-pattern stainless rod grates that hold sear marks deeper than the Weber Spirit's porcelain-coated cast iron, and double-walled lid that retains heat without warping at high temperatures. The cabinet has SAFETYGLOW knobs that glow orange when a burner is on — a sensible gas-leak indicator that costs Napoleon nothing and most competitors skip. Warranty is lifetime on cookbox, lid, and grates with 15 years on remaining parts, beating Weber's 12-year top end.
BBQGuys' Chef Tony measured 20-gauge stainless on the exterior hood and 18-gauge on the flame tamers and front control panel — heavier sheet metal than Weber uses on the Genesis. The WAVE-pattern grates are Napoleon's signature: angled stainless rods that produce thicker sear lines on steaks than flat or round rods, and that drain drippings sideways away from the burners. The flame tamers are tent-shaped to roll drippings away quickly enough that flare-ups are rare even on fatty meats — a real working advantage AmazingRibs called out when they noted 'flare-ups not occurring when cooking fatty meats like chicken.' This is industrial construction at backyard prices.
Rotisserie and Side Burner
Unlike most Weber grills at this price, the Prestige 500 RSIB ships with a complete rotisserie kit: motor, spit rod, two forks, counterweight, and the 18,000 BTU rear infrared burner that drives the cooking. Set up takes 10 minutes, the motor handles loads up to 20 pounds, and the rear infrared burner browns the skin on a whole chicken in roughly 45 minutes. The ceramic infrared side burner doubles as a high-output stockpot burner for shrimp boils or seafood pasta. Together the two infrared burners make the Prestige 500 noticeably more capable than the conventional-burner-only Weber Genesis E-435 for any cook that benefits from focused radiant heat.
AmazingRibs flagged a meaningful detail in their Platinum Medal writeup: 'rotisserie motor included with adjustable counterweight.' The adjustable counterweight matters because uneven loads (a whole chicken with the breast offset from the spit center) otherwise stress the motor and produce uneven browning. Napoleon's kit accounts for it; many competitor kits don't. The rear infrared burner sits directly behind the rotisserie axis so heat hits the spinning load uniformly. Combined with the SAFETYGLOW orange-glow knobs that visually indicate which burners are on at night, the Prestige 500 reads as a grill designed by people who actually use rotisseries weekly rather than as a feature checklist.
Build Quality and Long-Term Durability
BBQGuys' Chef Tony tested the Prestige 500 and rated its construction in the Premium class — 20-gauge stainless steel hood, 18-gauge flame tamers and control panel, lifetime warranty coverage on the main components. The smokedbbqsource.com tester called the build 'sleek but pricy — strong stainless construction and infrared performance that lives up to the price.' Owner threads on the AmazingRibs Pitmaster Club regularly feature Prestige 500s still cooking at year 10 and 12 — the warranty isn't theoretical. Where Weber's reliability story rests on the company's customer-service reputation, Napoleon's rests on the actual stainless steel grade. Both work, just differently.
Assembly and Setup
AmazingRibs flagged 'cabinet doors are difficult to assemble' as the biggest assembly complaint, and Home Depot review skim confirms it — owners report three to five hours solo and recommend a helper for the lid-to-cookbox alignment. Napoleon doesn't have Weber's slick Bilt app; you're working from printed instructions. Home Depot's $200 paid-assembly option is worth it for most buyers. Once assembled, the grill rolls easily on locking heavy-duty casters and the lid hinges feel solid through years of opening and closing — both the assembly pain and the long-term feel are well-documented Napoleon traits.
Where It Falls Short
Three specific gripes: the cast-iron warming rack warps if you forget to remove it before lighting the 18,000 BTU rear rotisserie burner, which is a known-and-documented Napoleon design quirk you have to learn. The small disposable drip pan fills with fat after roughly two long cookouts, which means a Costco-pack of replacement liners on the consumables shelf. The optional charcoal insert doesn't let you control temperature well — skip it and buy a separate kettle if you want charcoal occasionally. None of these are dealbreakers; they're the friction points that show up after the honeymoon period.
Napoleon's after-sale support also lags Weber's notably. Weber's 7-AM-to-9-PM CST phone line ships warranty parts on a single call; Napoleon's support is email-first with multi-day turnaround per multiple owner reports on the AmazingRibs Pitmaster Club forum. If your buying decision rests on a strong customer-service safety net, Weber wins that comparison. The Napoleon's lifetime cookbox warranty is the strongest in this lineup on paper but you may have to be patient about claiming it.
How It Compares to Alternatives
Compared to the Weber Genesis E-435 at the same price tier, the Prestige 500 sears hotter, includes a rotisserie kit, and offers a longer warranty — but Weber wins on assembly ease, customer service, and accessory ecosystem (WEBER CRAFTED griddle, pizza stone, wok inserts have no Napoleon equivalent). Versus the Weber Summit FS38 S at $3,999, the Prestige 500 gives up 181 square inches of cooking area but matches it on rotisserie and infrared searing for one-third the price. The pick between Genesis and Prestige comes down to whether you sear steaks and rotisserie chickens more than you smoke wings and grill pizza.
Who It's Best For
Buy the Prestige 500 if you grill thick-cut steaks weekly and rotisserie chickens or pork loins monthly, want a stainless-steel grill that will outlast your house, and don't mind spending a Sunday on assembly. Skip it if you're a first-time grill buyer (the Weber Spirit II E-310 is gentler at half the price), if you mostly cook burgers and weeknight chicken (the searing premium is wasted), or if you need WEBER CRAFTED-style accessory inserts (Napoleon's accessory line is thinner). For the right cook, the Prestige 500 is the most capable grill in this comparison short of stepping up to the Weber Summit. The lifetime cookbox warranty alone means this grill will outlast the typical 7-to-10-year service life of a competing Weber Genesis, so the higher upfront cost can amortize favorably over a 15-year ownership window.

- −Cabinet doors are notoriously fiddly during assembly per multiple owner reviews
How it compares
Beats the Weber Genesis E-435 on side burner output (14,000 BTU infrared vs 12,000 BTU conventional), rotisserie kit (Napoleon includes one, Weber doesn't), and warranty length (lifetime cookbox vs 12 years). Loses to the Weber Genesis E-435 on customer service depth and assembly ease. Costs roughly a third of the Weber Summit FS38 S while offering most of the searing and rotisserie capability for hosts who don't need the Summit's 681-square-inch capacity.
