Wherever one goes to school outside of the T14, employment opps. will generally be regional. That said, I won't speak on SMU only on why FSU makes sense for me in FL and the SE.
While I agree with a lot of what has been said (save for Alec's baseless comment), I think one should also note the ABA data and the up and coming nature of FSU's younger law program. If you look at the data reported by the ABA, they suggest that UF/FSU are neck and neck; in terms of entering GPA/LSAT, employment numbers (FSU actually better), bar passage (with Feb. test included), % employed in state (all three schools around 81%), etc. Miami is behind in most of these categories (although not by much). Miami does have the benefit of reporting higher starting salaries, however, this must be tempered with an adjustment for cost of living differences (e.g. http://www.bestplaces.net/col/?salary=100000&city1=5000&city2=8240
Obviously, I think Florida State is really good and I can only share reasons why I will be attending. Being from out of state (currently work in Philly), I knew I wanted to get back to the SE, find a school that's affordable, and wanted to be in a state capital (I think this is a really big benefit to any student in law school whether he/she wants to enter polics or working for the government) because of the opportunities it offers law students. I did not grow up in Florida and hence, am not really that aware of the whole Florida school rivalry situation. I did not apply to Florida (could not imagine being in Gainsville when not an undergrad) and was accepted at both Miami and FSU. The cost at Miami (imo) is ridiculous and unless you have a significant benefactor (I do not), I could not imagine one paying that much (exception being at a T14 school). Sure, the city will be more fun to live and you will have better job opps in S.Fla out of the gate, but you likely will be more distracted. Also classes at Miami are bigger, traffic/parking a nightmare, which all could interfere with studies.
With FSU you are betting more on an up-and-coming school and yourself rather than paying for a name, which it's fair to say is worth something (lawyers are self-preserving and will fight to the death to give their reputation the upperhand whether it's deserved or not). FSU's reputation has grow measurably and there are more and more students coming to FSU from out of state. As a result, I believe it's reputation and alumni base will continue to grow in step and rival that of the older, perhaps currently more established, UF and Miami schools.
At FSU, I believe I will be able to focus more on my studies (and in a rather collegial environment), worry less about finances, discover opportunities for networking, clerkships, and jobs that would not be present at the other two (save for corporate law in Miami). Taken together, FSU was clearly the top Florida school for me.
