Pellet grills and gas grills are the two best-selling categories in outdoor cooking — and they appeal to fundamentally different cooks. After running a Traeger Ironwood and a Weber Genesis side by side for a full year, here's the honest comparison every first-time buyer needs.
Quick Verdict
Gas grills win for fast weeknight cooking, searing, and reliability. Pellet grills win for hands-off smoking, real wood flavor, and weekend low-and-slow projects. If you cook 4+ nights a week, get gas. If you're obsessed with BBQ flavor, get pellet. If you can swing it, own both.

Speed & Convenience
Winner: Gas GrillGas wins decisively. Push the igniter, wait 8 minutes, you're cooking. Pellet grills take 10-15 minutes to reach grilling temps and require pellet hopper management. For a weeknight burger after work, gas is in another league. For a weekend brisket, the speed advantage doesn't matter — you have all day anyway.
Flavor
Winner: Pellet GrillPellet wins decisively. Real hardwood pellets produce genuine smoke flavor that gas grills simply cannot replicate. A gas grill with a smoke tube comes close on flavor but never matches a pellet grill's clean, consistent smoke profile. If smoke flavor matters to you, this single category settles the debate.
Searing & High-Heat Cooking
Winner: Gas GrillGas wins easily. Most pellet grills max out at 500°F — fine for grilling but not true searing. Gas grills with a sear station hit 700-900°F at the grate, producing restaurant-quality crust on steaks. Some premium pellet grills (Timberline XL, Camp Chef Woodwind Pro) close the gap with sear boxes, but stock pellet grills can't compete.
Low-and-Slow Smoking
Winner: Pellet GrillPellet wins decisively. Set 225°F, walk away for 12 hours. The auger feeds pellets automatically, the controller maintains temp within ±5°F, and the WiFi app monitors everything from your phone. Gas grills can smoke (with a smoke tube and indirect setup) but require constant fuel monitoring and never produce the same depth of flavor.
Operating Cost
Winner: Gas GrillGas wins on running cost. A 20-lb propane tank ($25 refill) lasts 18-20 hours of cooking — about $1.30/hour. Pellets cost $20-30 for a 20-lb bag and a long smoke uses 8-10 lbs — $8-15 per cook. Over a season of regular use, gas is meaningfully cheaper to operate.
Reliability
Winner: Gas GrillGas wins. A gas grill has burners, igniters, and a regulator — that's it. Failures are rare and parts are universally available. Pellet grills add an auger motor, induction fan, controller board, and Wi-Fi module — all electronic components that can and do fail. Pellet grids also require a power outlet, which limits placement and usability during power outages.
Final Verdict
If you grill 4+ times a week, mostly weeknight quick cooks, and care about searing — get a gas grill. The Weber Genesis line is the gold standard. If you're a weekend BBQ enthusiast who wants real smoke flavor without managing a fire, get a pellet grill. The Traeger Ironwood and Camp Chef Woodwind Pro are the standouts. Both grill styles will serve you for a decade if you maintain them.
Buying Advice
Most serious backyard cooks eventually own both. If forced to choose one, the answer depends entirely on cooking style: weeknight family cook = gas; weekend BBQ project = pellet. Don't believe anyone who tells you one is universally better than the other — they solve different problems for different cooks.
