I would make that decision based upon desired temperature. Very few of the smokers on your list can surpass the 485 to 500 degree mark. You’ll read a lot of discussion about grill grates helping you get into those higher temperatures and that product does work. I would simply pick a smoker that can get to the desired temperature you want like the Louisiana and the Memphis. Both can exceed 500 degrees and both can hit 600 degrees without problems.
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.
