it all depends on what one is into: cash games, NL/limit, SNGs, big buy-ins, wsop/WPT sats, etc etc
personally, im into NL tourneys, mostly WSOP/WPT/majors sats. i like stars and paradise and play almost exclusively there-love the software, the majors sats structure, the notes/stats features, etc.
i disagree with all of u. i think ultimatebet is the best poker site ever. they have loads of SnG tables and freeroll tourneys (about 6 a day or more). and most of the ppl there r nice and they wont cause ne problems.
Ultimate Bet has to be the best (for me any way) its got a good simple lay out, nothing fancy, which suites me, and correct me if im wrong but its the only site that has a buddy list to find your mates(dont make me cry if im wrong) (i dont play on other sites that often)
gamesgrid.com is a new however growin poker site. They have a 1000% first deposit bonus and they have a very frequent player bonus that if u play ring games for 10hrs in that week you get paid 1.5 time the big blind at the table on monday. They only have a few freeroles at night, but have games not commonly found like dealers choise, and are tryin to get h.o.r.s.e. tournys started
