I'm going to chip in my $0.02 as someone who lives in Ft. Lauderdale ~10 miles away from Nova, and has several friends attending UF dental and med. First off, if you choose to base your decision on location, I still think UF might win that contest. It's true that Nova is only about 20ish minutes from Fort Lauderdale beach (without traffic), but the actual location of the campus is in Davie, which is kind of a desolate area west of Fort Lauderdale. I mean the weather is still great, and if you're ever suddenly overcome with the urge to hit the beach it's nice to know that you actually can. Aside from that, I'd say the 5-10 mile radius surrounding UF's dental school is much more lively and fun. Overall, I'd say UF feels more similar to the classic undergraduate college experience (big school in a college town) whereas Nova is a much smaller commuter-style school.
As far as which is the 'better' school, is there really any question? UF beats out Nova in reputation, class size, cost, research (I think UF COD is ranked #4 in NIH research funding), boards....
I'm really not trying to hate on Nova at all. I actually think Dr. Lippman and the faculty there make themselves super approachable, and consistently try to accept applicants who will be team players and contribute to the cooperative student dynamic. I've talked to Dr. Lippman one-on-one, and he is really big on personality - you can have perfect stats, but they aren't going to accept you if they think you're the cut-throat type. I very much admire that, and I'm not sure the same philosophy holds true at UF.
Congratulations on your acceptances, and good luck with choosing the best fit for you!
