I concur with Caveman about Tufts being the most reputable school between those four. They are all around the same price, 30-35K for tuition, overall costs around 50-55K. If it were my choice between those private schools and my state school, I would gladly choose my state school and its tuition is 25K! The only thing that you may want to consider is location. NYMC is outside of NYC, maybe 40-50 minutes by train. Tufts is in Boston. MCP is about a 10 minute train ride from the heart of Philly.
I was accepted to NYMC and MCP and withdrew my interview offer from Tufts, so I had a similar debate a few months ago.
