Seeking advice - Buyside or IB

I currently have a two ft offers at a MM IB and a 3-5 years long-only fund. The fund requires a good standard of mandarin (i passed their test but not entirely comfortable speaking/reading mandarin on a day to day basis). The IB gig, on the other hand, seems to have a good culture based on my conversations with the senior management and associates.

For a recent graduate, which would you recommend? Thanks a bunch.
