While there's not a lot to dislike about pellet smokers, it really comes down to your cooking/grilling style. Some Smoking Geeks prefer pellet smokers to traditional smokers (or even the Green Egg style smokers) testifying that flavor is superior to that of other styles of smokers within the price range – and it's hard to argue with them. While Traeger is the pioneer, there are other brands that give it a run for its money.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
