Don't know much about UAMS, but given my desire to probably go to Houston(for personal reasons), I interviewed at UTH. I thought it was a well structure program with lots of autonomy and research opportunities (if you're interested) given it's affiliation with the TMC. The housestaff I met were pretty nice and laid back and the fellowship match list, while not impressive in terms of reputation, did show that they can get a good number of their residents into fellowship (primarily at UTH). I'm pretty certain Arkansas doesn't compare to Houston in terms of cultural/nightlife/diversity, but it really depends on what you're looking for. My 2 cents.
