I agree, but i would list Stud as second on the list behind stud8. I may be wrong. I would listen to an argument that Omaha is more difficult than stud, but imo stud8 and stud are the top of the list.

One reason for that being the requirement that the player memorize every card that is dead from probably 6 hands over 4 streets when betting on 7th street. In order to properly calculate the odds of an opponent having a straight or a flush one must KNOW what cards have been shown in all the hands that are now dead. That is up to 24 cards in every hand. That factor does not exist in Omaha or Hold-em.
