You should not only rely based on the ideas of other members, as simply they have their all time favorite that makes them work for them. But there are a lot of best online sportsbooks that you have to choose, and you can only tell which one will fit for you if you start exploring and making experience with them. Each sportsbook has its own great offers and bonuses, so try it with yourself and only by then, you will have an idea which works best for you.
I guess it depends, sometimes there are gamblers who aren't aware of the other sportsbooks that just launched recently and don't have time to create an account right away so they tend to rely on reviews. I don't see anything wrong in relying on what others have to say but I do agree that it's up to us to decide on which sportsbook is better than the other since we have our own standards.
I guess Stake and Sportsbet are the biggest and most popular in crypto, after all both are sponsors of English clubs! But I rarely bet there, mostly I am on Gamdom, BC, Betfury, Wolf... it's where I play other games and I always have some money for some sports bet! I don't have any complains, they are great for now, but I guess they lack some of promotions others have!
On top of that, they're improving their sportsbooks bit by bit, Sportsbet recently updated their horse racing markets while Stake recently added player props.
