Depends....

Will you have to go into an office or be home-based? Traffic can be pretty miserable, so if you have to commute, that will limit where you live (unless you like spending 90 minutes on the highway during rush hour).

The DFW metroplex is pretty big. Probably 100 miles East to West, and 50 North to South.

I'm partial to Fort Worth. Booming and expanding social scene and not as pretentious as Dallas. (If you ignore the TCU students.) Downtown/7th Street/Cultural District/Arlington Heights (not the City of Arlington; a neighborhood in FTW)/Camp Bowie West/Hospital District/TCU are the party areas. Downtown to Camp Bowie West is basically one long strip, and Hospital and TCU are not in the same area, but close.

Lots of new construction along 7th.

I live in Arlington Heights, and I'm a <8 minute drive from everything noted but TCU. (University area is more like 15ish.)

The City of Arlington is basically a pit stop between FTW and Dallas, sports stadia notwithstanding.

I could discuss the mid-cities and North FTW, but I'll hold off for the moment. I've already written a dissertation.
