Boston University, , University of Wisconsin–Madison, University of Rochester,which I should accept?

I’m a sophomore transfer student, and I got these three offers. My major is finance, and the cost doesn’t matter. I wanna apply Top 20 grad college. Which one is better? I used to prefer UoR, but I found there is no business school for undergraduate.

Guys, I need your opinion. I heard that Boston university is the hardest University to get grade.

anyone?
