If you or your parent are paying then CUNY is the better choice, if your employer is paying or you are getting a full scholarship then an Ivy League is there better choice. When I went to undergrad, I had a choice between Touro and CUNY (Brooklyn College) and ended up going to Touro because with financial aid Touro was cheaper.
The problem with med school is the expenses by the time you graduate you may owe 2-3 hundred thousands dollars and it may take 20 years to pay it back.
