I've also been accepted to NYMC, and I'm wait-listed at Downstate.
At this point, I'll probably choose NYMC offer Downstate. In-state tuition at Downstate is always a plus, but I think NYMC has much more to offer. The thing that draws me to NYMC are the clinical affliates in both Westcheste and NYMC- you can't get too much better than that. They also have strong committment to primary care, and community service. Their facilities are great, and much newer and nicer than Downstate. One drawback, though, is the curriculum (I prefer systems-based).
I wasn't too impressed with Downstate. Neither are many physicians that I've spoken with in the NYC city area (and that includes people who have attended Downstate). I thought that their facilities were incredibly run-down, and I'm not thrilled about the neighborhood- although you can't beat the demographics of the patient population.
One other thing that draws me to NYMC over Downstate is the demographics of the student population. NYMC's nickname is "UC Valhalla," and its name and reputation holds strong out West. This is importnat to someone like myself who hopes to eventually settle out West. My pre-med adviser (from a West coast college), didn't know a thing about Downstate's program, but raves about NYMC,
