Sorry for my silly stereotyping .... but I'm sure you can appreciate some do have a reputation!
I will be living around phoenix, so by saying its open minded is encouraging.
I live in Phoenix (moved here 6 years ago), and it's a lovely city (fifth largest in the U.S.). There are a lot of "family" here, and I'm not afraid to be who I am. Still a bit of a shock to see people walking around with sidearms, though.
Arizona is weird and very regional. People from Phoenix don't like people from Tucson (Tucsonians are whiny and don't get the whole "one person, one vote" thing). People from Tucson don't like people from Phoenix ("they get their way because their city is bigger, that's not fair! Just because no one wants to live in dirty, ugly Tucson!"). People from Flagstaff are stinky and unkempt (maybe that's just the university students...

).
The state is overrun with snowbirds during the winter (old people who move south for the winter), and they are pretty much universally despised as poor drivers (bumper sticker: "So many snowbirds, so little morgue refrigerator space"). Actually, the state is overrun with old people in general, which is why our politics is so whack-jobish (bitter angry selfish "I got mine" old people + entire communities solely of 'rose-colored glasses' people == teabag central).
The climate is incredibly variable. Phoenix (central AZ) is Low Desert, which is green and lush. Tucson (southern AZ) is High Desert, which is brown, dirty , dusty, and ugly (Las Vegas is also High Desert, for comparison). The northern part of the state is temperate and receives quite a bit of snow, but also has lovely summers. The eastern part of the state is mountainous and very pretty (snow, also). From Phoenix, you can get to any of these different climates in less than 2 hours.
tl;dr—Lovely state, glad I moved here, quirky people, relatively affordable.
