Texas is a really big and diverse state. There are very large remote areas, for example, with poor access to medical care and the schools in some areas may not be up to national averages.

However, I presume that you will not be choosing to move to a rural county. Houston has the worlds largest medical center and the neighborhood where I live has some of the best public schools in the country.

The web sites and newspapers that rank cities do so by using some sort of strange linear combination of factors, like so many points for having four distinct seasons and so many points for having professional sports teams and so many negative points for having more police per capita, etc.

I think that the best way to judge location attractiveness is to look at how people vote with their feet. The states that have a net gain in population have been judged to be better places to live.
