I prefer Omaha over Hold'em. I love the complexity.
This said I like the older style of play (a clumsy way of putting it) - a lot of players newly attracted to the game bring a simplistic take from Hold'em to Omaha. A pair of aces and someone will fly all-in preflop- then it all becomes a coin flip.
Here and elsewhere people make note it is a post flop game, but I think we are swimming upstream for the time being. If people prefer to gamble rather than strategize, it's their prerogative. So, even though I prefer Omaha, I presently play a lot more Hold'em.
