Hey, I got accepted to both, and if I were you, I would go to FIU. I was left with a good impression of the school during my interview. My interviewers are doing great in their profession (they were former students) and happy with what they told me, so I think not everything people say is true, especially on Reddit. I would keep the acceptance; they have good Miami hospitals to rotate, plus the class is smaller than Drexel. Miami is also a great city with so many opportunities to grow and collaborate. Congratulations.
Never accept the face value of whatever you read on the internet, especially reddit. The poster may have more credibility if they post here where experts can query further, but you are better served talking with students and alumni/residents.
Compilations like the MSAR, the ChooseDO, the VMSAR, or the ADEA DSE are essential tools to compare your application profile against historical trends,
