Michigan VS Wisconsin

[Shero]

I have been accepted to both University of Wisconsin (Biochemistry), Madison and University of Michigan (Chemical Biology)

I have visited both campuses, the madison campus left me a better impression than Michigan. I like their capital and frozen lake during the winter. In Michigan, I did not really tour around the city because of my busy interview schedule. I was mostly inside buildings and my hotel. So I did not really know what the town is like. I hear the college town is ranked the top 3 among the nation.

and the students in Wisconsin seem to be more friendly and chill while the students in Michigan seems to be more serious and competitive. I think I actually can fit into both environments... so I don't know what school should I choose... any advice?
