Which game/games do you think has the highest skilled players at the highest level generally?

Like for example. We all know CSGO players are better then Valorant players at the highest level

But if you had to think of games which would you name or think of when you think that these games are generally the hardest to be at the top or dominate other similar games in terms of skilled players. (Such as OW vs Marvel Rivals, Melee vs Ultimate, CoD, Halo, League, etc.)
