I prefer Omaha because you get dealt four cards instead of two . I like to draw to the highest hand possible on the board where I cant lose at the end.
No Texas holdem allows two cards gives us the ability to be deceitful about our holding, but at the same time we have the ability to put our opponents on a specific hand like omaha harder that holdem is hard to bluff at the omaha.
I'd definatly have to say Hold'em is my preference. Followed by stud or draw poker. I've tried a few times to get into Omaha. I can almost get into it if its not Hi/Low.
My favourite is holdem. And this is not cause of it's rules. I just see that much players play holdem and that's why I can earn some cash here. More players = more possibilities.
