I'm currently a first year at NYMC; I'll give you my opinion, such as it is, and you can do what you like with it.
Personally, I got a really good feeling from this school when I interviewed here, and I haven't been disappointed. I really like it here. The campus is gorgeous. It's out in the middle of nowhere, and you need a car (though I don't have one, and do get by), but you're also close enough to get into the NYC if you want to. Plus, you can live for years three and four in the city. I have lived in NYC for ten years and Boson for six, and frankly, I'm glad to be out of the urban jungle for a while, so I'm loving the separation.
My class is great. There are a lot of really cool people here, and in my limited experience, the environment is not cutthroat. But, it's early yet, so take that for what it's worth.
I have some excellent professors and some professors that I'm not thrilled with. The people in the administration (insofar as I've had to deal with them) are pretty cool, and seem to know what's up.
I have heard unequivocally, with absolutely no exceptions and no dissenting opinions, that this school gives you excellent preparation for the boards (step 1), and even the students (not just administrators whose job it is to sell the school) say that we are above the national average. It is unclear to me how much that holds true for step 2 and years three and four. It is year three that complaints about the school really begin, but for everything bad I've heard about the school for the clinical years, I've heard another student say the exact opposite, so the discontent may have something to do with the inherent subjectivity of clinical study. Also, a lot of the things don't sound as if they are specific to this school, but problems with clinical rotations in general.
First year, you're probably going to have to work very hard. I still have time to socialize and do other things, but everything is really intense. We don't have a pass/fail system, so if you care about getting high grades, you're gonna have to haul ass. But they let up on you a bit in second year.
In sum though, my outlook on being here is very positive. If you have any more questions, feel free to ask. Good luck with the rest of your interviews!
