Here's my personal ranking. Take it with a grain of salt.
UF>UM>FIU=UCF>USF>FSU
Maybe I just had a really bad interview day, but FSU made a terrible impression on me. They were disorganized, repeatedly emphasized that they have almost no research opportunities, and reminded us over and over that they would try to recruit all of us into primary care no matter what was actually best for us as individual students. The campus was nice, but it's in a sketchy area without very good clinical opportunities.
I have friends at USF, and they've told me that the classrooms aren't even big enough to hold all of the med students. Students who don't come, like, an hour early to class end up in a "spillover" room that only gets audio, not visual. They said it gets better after students start skipping class, but I wouldn't want to go to a school with such a bad set-up. I didn't bother filling out my secondary.
UF and UM both have good reputations, well-established curricula, good clinical experiences, etc. UF in particular has great learning tools, including an augmented reality anesthesia machine and fake human body so you can "see" what's going on inside them when you hold up a specialized laptop. I have a friend at UM who loves it and considers it the best medical school in Florida... "Except for UF, of course."
FIU and UCF are both young, but they seem very together, and it's exciting to be a part of something so new. I've only interviewed at FIU, but I absolutely loved the fully-integrated curriculum, the accessibility of online material, the location, the students, the faculty... everything.
When it comes down to it, I felt most at home at FIU (even though it's pretty far away from my current home), so I'll probably go there even if I get accepted at one of my "higher ranked" schools.
EDIT/UPDATE: I've talked to some FSU students, and I've been re-thinking my first impression. Every school's first two years will cover about the same material, so what really matters is the second two years -- and FSU has amazing rotations. They let their med students work directly under attendings, which results in a lot more high-quality hands-on learning. That's important because 1) it'll prepare you better for residency, 2) it'll prevent the burn-out that pervades less hands-on programs, and 3) it'll give students a better idea of what their future work in any given field could actually be like. I'm seriously considering attending next year.
