Full Tilt or Poker Stars
Pros and Cons
Poker Stars has better support - emails are answered sometimes under an hour - FTP takes hours
Poker Stars has more players but I think FTP has more skilled players
Poker Stars has an easier echeck process but I dislike how it shows "P Stars" on your bank statement - doesn't take a genius to figure that one out
FTP is faster paced - i.e Rush Poker
Poker Stars has personalized avatars
It comes down to preference. I've won more on FTP but still keep splashing the cash on Poker Stars. You could just play both
