I think it's best that you know all the rules of the game. So if you know roulette, for example, I think it would be the best, most fair.
Knowing the rules doesn't make it more fair than the others what if it's a live roulette there's no way to verify each bets since they're rolled by the dealer it'll just come down to trusting their operations. Online casinos have different ways of making their game fair but imo there's no clear winner of which game is the most fair.
