For me, the best choice is Texas Hold'em, because when I learned to play poker, I was playing Texas Hold'em. Also, I can play Omaha, but I do not really like it, and I'm used to Hold'em. As for all other types of poker, I do not know because I did not play them.
I think after Holdem. The best is Omaha, but I can not get used to to but sometimes I get confused,)))
I have friends who have already stopped playing Texas holdem, they say that playing Omaha is more profitable, I do not know how far this statement is correct, your question is a good alternative to find out if what they eally tell me is true
