I have mixed feelings about Arizona since i moved here a few years ago. As for climate, its nice when it isnt summer. When summer hits though, you are an idiot if you go outside for longer than 20 minutes. And then as soon as you get used to 110-115 degrees, a monsoon comes in. But its only one season of the year that sucks, so its probably better than most other places.
The geography outside Phoenix is great. Ive been to Sedona 2 times and its really amazing. Anyone that comes to Arizona should check it out.
The street system has been hard for me to get used to. When i lived in Austin there were lots of windy roads and lonely rural roads and they were very nice to drive along. Here though, its set up in a grid with each major street crossing at each mile. Causes tons of noisy traffic and its really hard to find a quiet place anywhere, even in the suburbs.
As far as the people go, thats the worst part. Its a mishmash of people from all over the US and for some reason that makes everyone unpleasant. The few natives ive met have been great, but they arent as numerous as the jerks from the rest of the country. Ive heard better things about Flagstaff though, and i may be going to college up there
Im rambling.
