Cornell or Michigan (need to choose fast)

Hi guys so I was luck enough to get into Michigan and Cornell (waitlist) and I have to choose quickly. I got into the most basic liberal arts program at both schools because I’m not sure what I want to study. I was accepted January 2018 admission to Cornell which is a little iffy because it seems like it will be harder to make friends. I know cornell is a little more prestigious but also very rigorous. I want to rush but michigans frat life is a little intimidating. Ann Arbor is supposed to be amazing compared to Ithaca where there isn’t much to do. Any suggestions at all? Anything would be appreciated and thanks in advance.
