You prefer a direct heat method of grilling: The Traeger grill uses an indirect heating source, much like an oven, so you won’t be able to sear meat, as many people like to do when grilling a steak. The Traeger system is better for those people seeking more of a smoker type of cooking system, although you can sear your meat by using a frying pan with a little oil initially before you finish cooking it with the Traeger grill. You can use the frying pan on a stove top burner or on the surface of the Traeger grill.
Traeger's, unlike other models, have a temperature probe, these sensors tell it if the temperature is too low and automatically feeds more pellets to the fire. You can set up the temperature in 5-degree increments. Other brands and cheaper versions only offer three settings low, medium and high. There is no sensor to monitor the temperature. If you are purchasing a pellet grill it is because you can set it and forget it. If you plan to hoover then it makes more sense to use a standard smoker or to transform your grill into a smoker.
