I may be biased but I will say for graduate school Buffalo is,better than Binghamton. Much bigger University with a much bigger research profile. We used to get snowy winters, it has changed, we get few isolated snow storms or isolated cold fronts and long stretches of mild weather. Of course in the summer, it is better than any place I have been to among 45 states. Not hot not humid just pleasant sunny skies. Social life in Buffalo Is better than Binghamton because Greater Buffalo Area has 1 million people and a dozen universities and colleges. Of course I don’t know what your field is, but with limited info I have I will say Buffalo.
