The gold standard is Carcassonne.
I guess that would make Ticket to Ride platinum.
TtR is also excellent, but not quite as polished I don't think. I wish the AI in TtR were better...right now, it's pretty awful, whereas the "strong" and "evil" Carc AI soundly trounce me about 80% of the time. In TtR, I play VanderBot Jr. and can win about 50% of the time.
I had some time to play Bang! this weekend, which I have not done in a while.
It is actually quite fun if you have 30min to an hour to play an online game. The built in communication system can actually get pretty funny. The online server is also more populated than before and you can usually find a 5 player game in 2-5 minutes.
