If you could pick a place to live in Arizona, New Mexico, Texas, or Colorado, which would it be?

We’re planning a road (plane) trip next month to check out 4 potential places to move. Considering Tucson, Boulder, Albuquerque/Santa Fe, and Austin TX. What are we leaving out? What are your opinions of these places in terms of natural beauty, affordability, economic vitality/growth-potential, and overall quality of life?
