I'm not a stud expert by any means, so this may be incorrect, but Mason has written on several occasions that one reason why there are more big stud games than hold'em is that in stud the antes get bigger compared to the big beat size than hold'em, where the structure is the same regardless of the bet size. This means in the big games, luck is a bigger factor. This allows the fish to win more in big games and somewhat counteracts the skill of the best big players. Thus, in the big games the variance is higher. This is not as important in small and midlimits. In hold'em, the people who play high limits can destroy the fish who want to play, thus there arn't as many big games.
