Fair?
At the moment, I would have to rate BeTheDealer as tops. I've made more money, percentage-wise, playing blackjack there than anywhere else. They pay out in five days automatically, like clockwork.
If you're looking for instant or almost instantaneous payouts, Phoenician and Nostalgia are great. Are they fair? That's debatable. Shark casino has one day payouts. Crypto's have one day payouts also.
William Hill may be fair. However, IMHO it has the worst CS of any casino that I have played. When I had a problem, live chat, phone and email did not work. I had to have the problem resolved through a third party.
