I have played on PrimeDice and BetKing. Both of them are great actually with better user interface and fast payouts. Dice games are best in PrimeDice right now and it is one of the top Dice gaming websites. 
I would say Primedice is the best to play Dice.
From my knowledge, I know of both Primedice and Stake which I heard are quite decent and unlike other dice sites you can also pay with altcoins (LTC and ETH). However, I also found this list which may also be useful: https://bitcoinplay.net/bitcoin-dice/
