i don't think there r so many tier-1 ib, usually gs and ms r recognized as 1-tier, others r 2-tier or 3-tier, DB,Citi,JPM so so, actually ubs is a litter better than the 3, traditionally there r 5 big names in the street, gs,ms,ml,lehman,bear stern. these years European banks r improving, u need to know more about he industry
lbs is the best finance school in European, while it does not mean that it's better than m7. Overall I think wharton,Chicago and Columbia r more reputable in the financial sector, but some European banks, such as db and barclays, may recruit a lot of lbs graduates from lbs due to location consideration.
overall, lbs is not comparable to wharton, chicago and columbia, even nyu is better than lbs, in my eys
