UM's median salary is inflated since they have a low reporting rate, so don't base it on that.
However, job oppurtunities (in terms of how much money you will make) are better from UM. They are in South Florida, which is the eight largest legal market, and has a good amount of BigLaw. Plus, they are top dog in SoFl. UF might be ranked higher, but UM grads are considered the smarter ones in South Florida. If you want to live in South Florida or try to take your degree out of Florida (UM places pretty well in the Tri-State area), then go to UM. If not, go to UF.
