Rothschild HK or UBS HK?

Received SA offers from the two, cant decide on which to take...

UBS:

Pros: one of the strongest banks in Greater China, great dealflow, the downsizing of UBS in the US and UK isn't affecting its Greater China operations much as it is still the top 3 banks in terms of ECM and completed M&A for Asia, average return rate for SA.

Cons: Sweatshop, really bad hours, HK IPO market is shrinking and will affect UBS HK as most of its revenue come from ECM.

Rothschild:

Pros: Great culture, small team, good dealflow, hire 1-2 SA per summer for HK, great exposure, hours are a lot better than BB banks in HK.

Cons: return rate is random and entirely based on your performance and whether the team likes you or not (they are not obligated to give return offers), last year they had 2 interns and none were given return offers

I still don't know which I should pick... Any ideas?

Thanks!
