These decisions are all based on personal opinions... You can simply say "cost matters, location don't" or "location matters, cost don't" and nobody can say you're wrong... I interviewed at both places and if i had to choose I would choose NYU simply because location matters to me. I admit buffalo is a great school, but it's very depressing. To me, if i have to study everyday in dental school for the next 4 yrs clinically and academically, then i would want to be in an exciting place so I don't get depressed. I would want to feel "oh wow, 4 yrs is gone already?" rather than "thx God!! it's finally over" for my dental school experience. The bottom line is, decide for yourself, SDN can help you get more familiarized with the school's programs, but the location & cost decision is up to you.
