I've had a BGE for about 15 years. My family gave me a high dollar Traeger last Christmas. I bet I haven't used it a half dozen times. Pellet grills are basically ovens. It's for men who don't know how to smoke or grill, but want to cook outdoors.
They are very easy to use, but you don't get hardly any smoke flavor. Power is also required to cook. If the power goes out mid cook, you are SOL or going to the oven.
YMMV but that's my 2 cents worth on pellet grills
