My neighbors have a pitboss and love it. It has features on it that my Traeger does not and was cheaper. I do alot of cooking outside and have a weber genesis gas grill, blackstone griddle, and traeger pellet grill. If I had to choose just one it would be the pellet grill.
Searing items on the gas grill is the only thing it can do better than the pellet grill. I use the blackstone more for items you can't use a grate for, stir fry, breakfast (eggs, pancakes, etc).
