Congrats! Having these kinds of options at this point is excellent and is a good indication that your future is bright regardless of which school you decide to enroll in.
I would say it depends mostly on what you are looking to get out of your business school experience, each has several pros and cons, however it does look like Cornell has the biggest benefit financially and I will say that based on your indicated professional interests, Cornell does extremely well placing high caliber candidates such as yourself into major IB positions for the summer. I will also say that they don't just do very well getting students into IB positions for the summer, they do better than most schools in getting those students full-time offers which is the next and ultimate goal for most aspiring I-bankers.
I'd suggest that you look at some of the posts on the Johnson thread, ask a current student, and/or talk to an alum to verify my obviously biased opinion, but I think you'll find that Johnson does extremely well in the I-banking sector in NYC.
