I have the Rec Tec RT 590. The RT 340 is the smaller version of this one. All stainless steel, excellent controller with dual food probes and fantastic customer service. I don't know anything about the Camp Chef. I have owned several pellet grills and I have found that the RT 590 is one of the best I have owned. Temperatures across the grill great are within a degree of 2 of set point. I have verified this several times with different temps and cooks. I have the Davy Crockett tailgate grill and I am going to end up buying the RT 340 as it is bigger and with the great wifi and other improvements it is a no brainer for me. I will be "gifting" my Davy Crockett to my other son. The one in Florida has already received my Blaz'n Grill Works Grid Iron and Traeger junior.
