Thanks for the additional thoughts, everyone.
I know, it was just so bizarre to be waitlisted and then accepted, with, actually, substantial scholarship money. To everyone going through the application process, I'd take it as a huge sign that you really should be aiming to apply in R1, because if you get waitlisted, you might then get accepted in R2 and have much better chances to get to know the school. Obviously, it's better to submit a strong app in R2 than a weak one in R1, but it's best of all to plan far in advance for R1.
Just for the record, I went with Ross. I'm positive I would have gone with Booth if I was planning on finance or consulting (they send more people to MBB every year), but I'm not. It was an excruciating decision to give up my former top choice, but I went with comfort level/culture/100% tuition in the end, especially considering the fact that the vast majority of people whom I consulted told me they don't perceive much of a difference, if any, between the two schools.
