I guess I'm among the few who was NOT a CCS fan when I discovered TRC. I've been a big CLAMP fan for a long time, though, so I was aware of it when it came out in the US, but didn't really pay it much attention, thinking it would be similar to CCS or confusing to follow for someone who wasn't familiar with CCS. I was more interested in Legal Drug and XXXholic.
Then I kept hearing from fans on different forums how good it was, and ending up playing in a TMM/TRC crossover RPG on a Tokyo Mew Mew board. I started getting really curious after that, and when I heard there was an anime coming out. So my next trip to Waldenbooks I picked up the first volume of TRC, debated a little while, decided I'd probably regret not buying the next volume of X instead, but since it was CLAMP, it couldn't be THAT bad, took it home, read it, and the rest is downhill from there. ^____^;
