FWIW, I'd steer you away from Jacksonville. It's got all the "Big City" that you'd want to leave behind, I suspect.
If I had a choice and was going to live there anyway, I'd do the panhandle, Valpariso, Destin, Eglin AFB area or west of there, or at worst Lauderdale if you like the city stuff. Kinda depends on what you do for work, though..
