Don't own a gas grill but that nap sure looks like the cadillac of gas grills,I get the benifit of a gas grill,quick n easy peasy to use,but can't compare the flavor to good ole charcoal grill meats,I do have a pit boss pellet grill which I seldom use,its okay for a few things but lacks the smokey flavor I get from my weber charcoal and wood chips,MOP on pellet grills is they are over rated,pit boss has built in searing which sold me on the grill as treager only reaches temps to 440 degree's Green mtn pellet had propane side sear for steaks/burgers.,but pain in the ass dealing with propane.
issues with pit boss when searin at or above 500 degree's is flare ups,even started my pellet box on fire searing steaks,pissed me off,always vacume the fire pit out before each use so not sure why the fire,so my weber's get the most use year round smokey joe for steak,chops chicken,big kettle weber for roasts,ribs,turkey and rotissari cook outs with various wood smoke.
