I'm not sure about UF exactly, because I didn't apply there, but I know for the other schools I did apply to, post-Dec interviews are considered to be equally good. To a certain extent they could be considered better, because then you don't have to wait til X date to find out if you were accepted or not. A school I interviewed at told me that whoever interviews after Dec. 3rd, say they're interviewing on Dec. 4th, could find out if they were accepted on Dec. 5th.
Good luck though, and be confident with your interview, and I'm sure it'll all work out in your favor! 🙂
