Smokers
I have no experience with propane smokers, although I went from a propane Weber BBQ, to the electric Pit Boss pellet grill. Since getting the pellet grill, my bbq has become a yard ornament. As far as the digital vs analog controller goes, get the digital. They have much more precise temp control. We had first hand experience with this on my Dads Traegar years ago, it came with analog, we quickly switched the controller out for a digital one and were very pleased with the results.
