Boston University or UW Madison?

First of all, please forgive my poor English…
Hello, I’m an international student. I’ve accepted to BU and UW Madison (both college of engineering).
My goal is to study Brain Computer/Machine Interface at a graduate school, so I plan to study electrical/computer engineering or biomedical engineering at undergrad.
I know that BU has a top-notch biomedical department, but UW-Madison has better engineering department in general.
So, my question is which university should I go in order to go to great grad school such as MIT or Stanford? I really don’t know which to go…

I appreciate any comments!!!

Thank you!

PS
money isn’t problem for me
