Punk. Go to Chicago if you want to be a master expert with mad skills. Kellogg is for marketing wanna-be rejects who spend their time shopping at the GAP. The GSB is for leaders.
Just kidding. Go whever you want. Just don't come crying to me when your Kellogg "degree" gets mistaken for a Cereal box affiliation.
Just kidding. Seriously, you should evalute both schools as best as you can and pick the one which is best for your long term goals, which if you have any brain at all, is obviously the GSB.
Just kidding. No really, take a good hard look at culture and figure out what fits best for you. If you want to be a pansy hippy go to Kellogg, if you want to be a god amongst mortals, go to the GSB.
Just kidding. Really. I'm just bitter about my Kellogg waitlist.
If you ever wanna get together for a drink let me know - I live right near the downtown campuses.
