It all depends on what you want out of your education. If the DO program is more PBL and that's how you learn best, go with that. If you're an MD homer and want those letters behind your name, reapply allo next year. I will say I was in your situation not too long ago and the tuition/COA difference between MD/DO was enough for me to wait on an MD acceptance. For what it's worth, FSU COM stats are increasing significantly (the MSAR is kind of a crappy resource) and the school was ranked last year as one of most competitive medical schools to get into in the nation. A good friend of mine graduated ugrad with a 4.0 GPA and an equivalent of a 32 old MCAT and got denied from FSU COM the first time, she worked as an MA for her gap year, reapplied as soon as the app became available to submit, and got in within a week of her 2nd interview; nothing else changed on her app. I'm the biggest FSU COM homer so I'd say it's worth reapplying, but go with your heart.
Sorry if I missed it but: Did you interview at FSU this cycle? Are you from Florida? When were you complete this year? I will say that if you're not from Florida/no ties to the state, you'll have a hard time getting any love from FSU. Let me know if you have any questions
