The best part of the country is relative to what one considers 'best.'
For example, being raised in the Mojave desert, I consider the southwest part of the country the best. The northwest is too rainy, and the east is too humid.

Mesa, while located in the southwest, is far from being close to the top of my list, so I could not recommend them.
