Would you prefer Thammasat or Chulalongkorn for an exchange semester in Bangkok?

I know Chula is a little more prestigious, but I like Thammasat. The quality of the education is not the most important factor to me. First and foremost, I 'm looking for a nice place to live and get to know friendly people. Ideally, the University should also be well organized and I would like to be able to speak English w/ many people. Thanks
