Pokerstars looks more reliable to me. In different rooms there are such cases: Cases of unjustified blocking of accounts. Blocking for far-fetched reasons in order to prevent money withdrawal is practiced by fraudulent sites.
Integrity of the game - using a certified random number generator (RNG), fighting
poker bots and supporting programs that provide a gaming advantage to opponents.
Accessible verification - identity verification within the time frame established by the user agreement, according to documents that the user can provide, taking into account the country of residence.
