I would select the school that gives me the best education and the best opportunity to succeed in medical school. In regards to psychiatry, I would hold off on putting all your eggs in one basket. I can't tell you how many people, including myself, changed "careers" from the onset of medical school to now.
I can comment on NSUCOM since I attended there. No doubt in my mind, with all the struggles my classmates and I went through, NSUCOM will PREPARE you to be a doctor. How great or good of a doctor you want to be determines how much extra work you are willing to put in. I personally felt NSUCOM gave me a solid platform to jump on. Yet, I would look into the school. They just underwent some faculty changes. I would inquire what changes are being made and how they will affect the students. ASK CURRENT STUDENTS!!!
