I have the RecTec Trailblazer and it is wonderful. LOTS of stainless, a great controller, WiFi, two meat temp probes and great customer service. I can't say enough good about this cooker. I use it about two times a week, and so far it has been flawless.
To me it is the best value small cooker out there. I really appreciate the longevity / lack of rust with the stainless, and the controller / WiFi / meat probes are added bonuses.
I really can't think of anything negative to say about the Rec Tec, although some people really dislike the bull horn handles. I'm not a big fan of them, but that was a small concession when I considered all of the advantages of this cooker.
I believe that you will be pleasantly surprised and happy with any of the cookers discussed. Just decide what's most important to you, and then buy the cooker that checks the most boxes on your list.
Good luck, and welcome to the world of pellet cooking!
