I like buffalo, its cheaper! Especially the cost of living! If you are in-state, it's WAY cheaper, If you are out-of-state Buffalo is still $40,000 cheaper than Nova, so thats a decked-out Lexus cheaper!
Honestly both programs are very good. It all depends on which suits you and your preferences better. Sure Nova is more expensive but if you would be happier at Nova you'd probably do better there and it would pay off in the long run. I would personally choose Nova over Buffalo bc of Buffalo's weather - not for me. Nova has an amazing campus and its reputation is generally very good. The choice is yours - dont let other people make it for you...
