Well, word 'better' can be interpreted in multiple of ways. If one would count area coverage, than nothing compares to Tokyo, but a place which has 'women only' cars give some thoughts.

The only thing I wish MRT could have is later closing time. Especially now, when due to sleeper replacement number of stations close at 11:30PM. In my worldview, main transport arteries should operate at least till 1AM, but hey, in Tokyo trains stop running at midnight as well.
