I actually was a
Party Poker guy for 2 years but
poker.com won me over with it's great bonuses, freerolls and satelites, great chances to satelite into WSOP or Aussie Millions this year. Great comps and the bonus wasn't to hard to clear.Also helps that you can find some easy competition at
poker.com. As far as graphics and avatars I believe
Full Tilt blows away the competition.
Little update info: Join this site if you want great chances to go to WSOP. For only 60 bucks you can play 5 people and get into the WSOP. Or if you can't spring for that money, spend 2 bucks satelite into $11 tournament, win that and then you are in the $60 for only $2. You guys have to check it out.
