Having interviewed at OSU and Cincy, as well as knowing several people who attend each school, I don't see a big difference between OSU and Cincy. I cannot comment on Penn State as I cancelled my interview. OSU has a higher ranking (~30), much of which was gained in the past 5 years, while Cincy (ranked ~40) has a brand new building and several strong hospitals within walking distance. They both have reasonable real estate prices and are great teaching centers. I would imagine OSU has more research opportunities and other benefits that go with being part of the largest public university in the nation, but not sure how much that matters to you. I honestly think as decision like this is a personal one, regardless of the advice people like us give to you. I also think that you will find the prevailing opinion on these boards to be for OSU, and I'm not sure how much of that is an informed opinion or people just repeating what school is more highly ranked. But go with what you gut tells you. I can't see you going wrong at any of those schools.
