How much is the scholarship?
There definitely IS a cultural difference between the schools, and it shouldn't be underplayed. A lot of the closed list dinners I went to for recruiting were a mixture of Booth and Kellogg, and the difference in student cultures was palpable.
Booth people like their school for the most part, but they definitely are geekier. If that's your personality, you should have fun there though. Likewise, Kellogg is mostly extroverted people who like to party and socialize 24/7, if that's not you, you may not like it. A lot of self-segregation goes on when people apply/choose among cross-admits.
For the bottom M7 schools (Kellogg, Booth, Columbia, MIT, + Tuck), the recruiting is exactly the same for consulting, so don't worry about that aspect.
