I am not saying all decentralized casinos are good and I am sure some of them could be not good enough to rival the others but they just have a feature that automatically puts them above many of the casinos. Of course, places like stake still holds their own because they have been in this far longer than their competition and they have been working without a complaint for years now which makes them far superior than any of the other options we can provide.
If you want to remove the trust from the equation then you can definitely go with the dapps that are gambling and decentralized which would make you not need to trust any website at all, since its decentralized you don't need to trust them since they are not operating or controlling the casino at all.
Moreover, if you want someone to hold the casino and want to trust them because then you will get to see years of experience then you can definitely go with places like stake because those guys are not decentralized but trusted more than the decentralized places combined. I feel like stake has achieved what no other casino can achieve for so long that they earned their place (with primedice too of course).
