Cologne has one of the best systems. It's fast, comfortable, reliable and not too confusing. I did take a train to the completely wrong direction at one point, but that was my first visit to the city. I had just stumbled out of a long-distance bus after getting 2 hours of sleep on there and took a train to Merheim instead of one to the central station.
What I don't like about the system is that it's very cold and soulless. Most stations look the same and they have that robotic voice that keeps mispronouncing /ʃ/ as [ʂ].
