Hmmm it seems like what I've been seeing about sportsbet.io is true since you didn't mention them on your list. I have been seeing some people that complained that sportsbet.io never paid them their huge winnings, instead they will block (I only saw a few people that said this). But a lot of review sites I see when I research on Google always mention Sportsbet as one of the best betting sites. Most of them even put them as the number one, while CloudBet is then placed at number two position.
I would suggest you to stay away from sportsbet because they have some issues. Although they do pay you but they hold your amount in case of larger wins and this makes them a bit fishy. This has been told by few players who actually play at sportsbet. You can use clouldbet or onehash for sports betting.
