You need to clarify what you mean by "here" and what part of the US you are talking about. The US and Europe are big places and the transit systems are as different inter as they are intra.

The Paris Metro is an absolute run-down antique compared to the trains in Seattle. It would be silly for me to declare that all European metro systems are therefore run down and tatty. If I compare the Barcelona metro to New York, it makes Europe look great. Meanwhile the London Tube is cramped, frequently dilapidated and has its own species of mosquito.
