I don't know they are both good, like sourcOP more right now because it is full more often. When sdogg gets his rotation server up though, that is where I will be going for my all-maps play. Also prop-hunt once he gets it.
No offense to sdogg, but I don't know how excited I would be about switching servers and losing my stats, but the people is more why I play on sourceOP so if everyone switches I will as well.
