I hope Full Tilt and Ultimate Bet will make a return to the US. Full Tilt had incredibly stable software, and was reliable with the payouts. Ultimate Bet was reliable too aside from the 'potripper' scandal, which was a wake-up call to the industry and the players. So right now, as a US customer, I'd say Carbon, Bovada, Black Chip, Full Flush, and Heritage are good choices. Heritage has what I consider the best sportsbook as well. Juicy Stakes' cashout fee is a joke $100, so until they lower this I won't recommend them to my peers.
