NYU is a private, dental factory. Unless you're going to live off your parents for 4 years while living in NYC and learn a lot on your own, I would go to Michigan. Considering what took place in 2005, I'm not too sure all of a sudden...
I've come to realize networking doesn't mean shiz. Do good dentistry and stay alert to new, effective techniques. Dentists don't give shiz about what school you graduated from. As long as you strive to be a good clinician and business manager, you'll find a good mentor to work with. You'll open a practice in 4-5 years after you graduate anyways. A lot of dentistry are self-taught, I think.
By the way, I don't go to NYU. Maybe this wasn't my place to say anything...
