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.
One other thing to know about the wonder of pellet grills is that they come with pellet hoppers, varying in capacity from brand to brand, that accommodates and use the pellets you put it accordingly and automatically as per the heat setting, eliminating the need to refill the hopper manually so frequently. So throw on some lamb ribs on to those hot grills, and go enjoy some cold beer while the pellet grill does the rest for you!
If you are looking for the perfect spacious grill for home cooking, then this Traeger grill is yours for the taking. This is the most sold and famous model of Traeger grill in the market currently.

It is built to last with sturdy steel construction with a powder coat finish. Additionally, it has a non-stick surface that makes it easier to clean and maintain the grill grates. Moreover, it is 418 square inches, enough for 16 burgers, 5 racks of ribs and 4 whole chickens.
I did a lot of research, and ended up buying the Camp Chef DLX24. It was at a price that fit my budget, (under $500) and had a lot of features the others didnt. The pellet trap door for quick dumping of the pellet hopper into a bucket, and the ash cleanout under the drum was a clincher. Being able to pull a lever and dump the ashes into an easily removable cup is a great feature that all grills should include.It has a digital temperature controller, and dual probes (one inside the smoker for grill temp, one for the meat) and overall good quality construction. The second shelf inside is standard (you pay extra for that on other grills). If your budget allows, would suggest purchasing the propane powered sear box ($199) which attaches to the side of the grill and allows for reverse searing meat..
With 341 square inches of cooking space and a digital control board that sets the temperature from 180 to 500 degrees, you’ll be cooking whole meals in this grill, even though it’s the smallest model that Pit Boss makes. It will hold up to a dozen burgers for parties, or a chicken and vegetables for the family dinner. When cooking is done, the porcelain coated grill grates are easy to clean.
