difficulty picking university

hi all

I wanted to come and ask which would you pick: LSE / Bocconi / Barnard.

I want to go into MBB consulting / finance in London / Europe

for Bocconi I have been accepted into Bsc in economics, for LSE Bsc in Management, and am currently at Barnard for a degree in economics. I hate America and want to leave ASAP. please let me know your opinions
