I am actually in a similar situation. Disregarding the money issue since they both are soooo expensive, I'd pick NYU. When I was at USC for the interview, I asked the admissions staff what the passing rate for board exam was and she was hesistant to answer my question. She ended up saying "Yeah, it is not as high as we'd like it to be..." Their PBL sounds interesting at first but I personally don't think it is the best method.
Besides, I love NYC!
