I find the people of Cerberus to be really nice, for the most part. Lots of super kind people in my FC. The most attitudes I encounter come from DF parties and I suspect some of the most rude people are probably americans :P

That said, I'm also american and ended up on a different server because of over-crowding. I'll probably end up staying because I like my FC, but I also have the problem of not having people to play with most of the time because of time difference.
