Hmm very difficult decision.
When you say finance, what do you mean, exactly? Booth places really well into IBD (I'm sure Tuck does as well but don't know for sure). Tuck punches above its weight in terms of PE recruiting because of the incredible network. Not sure about ER, AM, etc.
Where do you want to live long-term? If you want finance, I'll guess NYC. Then maybe Tuck makes more sense. But if you want to do finance in the MW, maybe Booth makes more sense.
You have no location preference between the two? At one you'll be living downtown in America's 3rd largest city (and should be considered 2nd largest since LA doesn't really have a real downtown), while at the other you'll be living in the woods. VERY different.
Overall, I'd say go with Tuck.
- Save $50k due to full scholarship vs. Booth
- Be closer to NYC for finance
- Better network
- Maybe have a shot at a PE gig given Tuck networking
