UCL vs Boston College (US). UK VS US in general too.

If you're looking at it from a prestige perspective, UCL is a highly ranked university not only in the UK, but the world, Boston college not so much. Financial institutions especially investment banks tend to hire graduates with the prestige of the uni they attended being a factor.
I have a few questions so I can give you some more specific advice.
Are you from the UK? If you are from the UK, would you be paying international fees?
Also, why do you want a US university experience?

Hey, I go to secondary school in the UK and have a British passport but am applying as an international and paying international fees as I was told it was easier to get into the universities. I want a US university experience because firstly I’ve lived in the UK for about half my life and living in London and seeing all of the university students in London, it just seems kind of depressing and boring. I also have a lot of friends both currently attending and about to attend both US and UK universities and the US ones have always seemed much more content about their university life (sports, culture, friends) compared to the UK students who seemed to only be drinking and partying in their free time. I would also like to work in New York eventually in finance. The final added bit that makes me prefer the US is that I just don’t like having my whole life depend on my A levels and I still understand that the US universities still would like me to get near my predicted grades but they wont rescind my offer if I don’t.

I have just gotten an offer from UCL for HPE but am really trying to go to the US. I got waitlisted from NYU Stern ED2 and now one of my top choices is Boston College. If I do get the acceptance from Boston College should I accept it or do UCL? I am predicted A*A*A* in Economics, Politics and Maths and my UCL offer is AAA. I’m quite confident I can achieve these grades in economics and maths but although predicted A* my politics grades can be quite volatile and I’m scared on a bad day it might drop to a B. I have also applied to Columbia, Cornell, Northwestern, Northeastern, Boston University, U Michigan (Ross), UC Berkeley, UCLA, UC Irvine and UCSD in the US. In the UK have applied to LSE (Politics and Economics), UCL (HPE), UCL (PPE), Kings (Political Economy) and Bath (Politics with Economics). I have only gotten decisions from UCL (HPE) and Kings (Political Economy), AAA and A*AA respectively. I really want a US university experience but don’t really want to sacrifice university prestige or career prospects (in finance) for it. Anyone’s input would be greatly appreciated. Thanks.
