UB and FTP are the only two (I believe) that has rakeback and supports Poker Tracker. FTP has, IMHO (and I've compared to several others, INCLUDING PokerStars), the hardest small stakes NLHE games on the net. The stakes you play are somewhat easily beatable on any site though. However, in my experience, the transition from $.25/$.50 to $.50/$1 to $1/$2 is very tough on FTP. There's a huge difference between game quality at each level. Ironically, I feel that $2/$4 is easier than $1/$2. Someone pointed out that that might be because you have mainly a bunch of college students that know how to play poker but don't have much money playing at the $1/$2 level, and $2/$4 is where the real "gamblers" start playing (i.e. fish that usually play in a casino). I think he might be right.

EDIT: Oh man, I just realized that you're not an american and Party Poker is available to you. You'd be INSANE to play at any site that allows U.S. customers if you can play at Party!
