Sorry, I don't know much about NYIT except their class size is decent (40 - not big or small). I didn't apply there because of it's location, but I got into LIU. So all I can say is that I really liked LIU. I went to an open house and then obviously for my interview and got a great impression of the school both days. The professors were really easy to talk to and seemed like they could offer a lot. Also, their class size is smaller which I like. And I spoke to some current students who loved the program and had great things to say about it. I think it's a really good option, but I can't really compare it to NYIT because I don't know anything about that program.
Hope that helps, or at least makes you more confident about LIU =\
btw - I'm a fellow Rutgers grad =)
