Which of these colleges could I brag most about going to?

Please just pretend this isn't so immature. I have to choose between Georgetown, Northwestern, and the University of Chicago. I want a college where, if I get into an argument with someone, I can end it with," Yeah, well I went to ____________, sucka foo!" Yes, I know you should never do this. And I know you should pick a college based on if it is the right fit for you. But, ignoring that, which one of these colleges best fits in the blank?
