If I had gotten into Booth, I was going to personally choose Kellogg over Booth (I wrote about it a bit in my "Share your application experience" thread before I got the Booth reject). I too want to switch into Management Consulting.
The reason I felt this way was for two main reasons: I wanted a close-knit student community, and I wanted a collaborative environment away from finance people. I went to Stern for undergrad, which had both not a strong community (people lived spread out throughout NYC) and a cut-throat finance experience, and contained people with poor social skills...I really didn't want to repeat that experience.
People have posted the Booth community has improved the last few years, and people are very supportive nowadays, but honestly I wasn't going to risk it. I've worked in investment banks for 5 years, and I know what those type of people are like (in general), and I don't want to be around those type of people anymore.
For you personally, I'd visit both schools, it really comes down to what type of culture and environment you want. There's plenty of things in Booth's favor...newer building, marginally higher rank, flexible curriculum, urban instead of suburban environment, etc There's no obvious right choice here - they are peer schools and both place great in MC - so it's just going to have to come down to your subjective feelings.
