Morgan Stanley HK vs UBS London Sales and Trading summer internship

I have received an offer from UBS and a superday invitation from Morgan Stanley. I am quite unsure whether I should go to the superday (given the long journey to Hongkong) The UBS S&T internship allows you to rotate across different desks and it is located in London. On the other hand, the full name for S&T at Morgan Stanley is Institutional Equities, Prime Brokerage and Bank Resource Management. There is rotation, but I do not have the choice of interning on the FICC desks. It is located in Hongkong. Obviously, MS has a bigger brand name, but limited in the desks I can choose. To you guys, which offer for summer internship seems a better choice? ( I prefer trading than sales/structuing) Thanks!
