I have personally been to both schools. They both have great but vastly different locations. There are major differences between the schools and what you decide is right for you may be different to someone else.
I highly suggest you go visit both schools again (yes i know this is expensive) sit in on a class, talk to students without the pressure of an interview. See what atmosphere is best for you, that will greatly determine your happiness.
For me I loved CCOM, but I also loved Nova. Given the choice which I don't have since I was rejected from CCOM, I think now I would choose Nova.
For me CCOM does not record their lectures which is a large problem, I like to relisten to them. Also CCOM seemed a little more stuffy (please no one take offense) when I was there, Nova seemed more laid back. CCOM seems to have a better reputation but it will all depend on how YOU do in school and on the boards, so where you went to medical school won't matter as much.
Unfortunately, the only one who can make this decision is you. Make a list of the positives and negatives for each school and I know you will make the right choice for YOU.
