I think H/L is just as difficult as Omaha, but they are played completely different. Where as you are fighting for the whole pot and only the whole pot (the very occasional split), in H/L u r sometimes playing for 1/2 the pot and trying to quarter and make sure ur not quartered. If the players are weaker in H/L than regular, this may be the reason why u r doing better in H/L than O. in that case keep playing H/L, I think it depends on the quality of players u r playing more than whether 1 game is more difficult than the other. I don't think results should judge why one would be easier. That would be like saying I make 10/100bb in HE and -2/100bb in Omaha so HE is easier than Omaha. I'm not saying that ur right or wrong, im just saying that ur results do not judge whether or not a game is easier overall (although it might be easier to u)
