IMO Players Only
is a very good site. Young but good. They also have some pretty good incentives. Freerolls
there are pretty good too when they have them. They host a $1k freeroll 4x a week usually. Deposit bonuses are about the same everywhere however some sites' requirement to fill those bonuses are easier than others. For instance PokerStars doesn't give partial FPP for low buyin tourneys where as FullTilt and Players does. So at those 2 sites it is easier to accumulate the points neccessary to claim your bonus.
