Which one has the best COMPUTER SCIENCE program? Purdue vs. UWisc-Madison vs. Virginia Tech

As a repeat, which school of the three has the best COMPUTER SCIENCE program? Purdue vs. UWisc-Madison vs. Virginia Tech?

I have gotten accepted to Purdue’s computer science program so far, and I’m sure I will get into Engineering college of Virginia Tech as well. I’m not certain about University of Wisconsin Madison, but if I had gotten into both of them, which one should I choose? Could you rank in order?

Thank you.
