For a short couple year stay, yes. Long term, no. Global warming and water shortages don't make AZ a viable location to live. It's just going to get worse and worse for the southwest. From an ecological perspective, I'd live in the northeast or south east.
I've lived in both (currently in Houston). I think it's worse in Phoenix than Houston. Your body gets acclimated to pretty much anything, but once you reach past 110, it's just too much. Yeah, in Houston you feel sticky and you have to get used to having moisture on your skin all the time, but you get used to it. When I travel to less humid places, my body kinda feels weird. You get used to having that moisture on your skin all day, and when it's not there, you feel strange for a period.
