While I agree that Taipei's MRT is EXCELLENT (in my opinion the best in the world - and I've travelled all over the world), Hongkong's MTR isn't too bad either. I will rank it as among the top 5 in the world. Even though it is very crowded, people still line up in an orderly fashion and there's no eating and littering in the train. I've used Beijing's metro during rush hours, and honestly it was HELLISH. I was literally KICKED by someone - a woman who also screamed and swore at me just because I wasn't exiting the train fast enough (because someone was in front of me blocking my way). It was absolutely the most terrifying and humiliating metro experience I've ever had in my life, and I have used some really bad metro systems (e.g. New York's).
