I have only played at Party Poker so far. But was considering Poker Stars. The card dealing on all sites seems odd at times (Thats poker) but having measured it on Party Poker (Over 1,500 hands)it is about spot on with probability. None of the 4 aces losing to a royal flush nonsense. Only gripe about Party poker was paying up on affiliate accounts. Still owe me over $1,000 and making loads of excuses as to why not to release the money. (Your players have not given us enough money yet!) Any more stories on PP failing to pay up?
