It depends on what your good at, I know player who can take down in NL hold em but are dumb founded in Omaha (this is actualy common), I also know players of PL omaha who cant play NL hold em(more rear , I think many start with hold em and then learn omaha later, some players are great in both and they tend to be real good in both, I think you can find more fish in hold em, i know hold em player who never even heard of omaha... and when I meet them I always invite them to a game with me bahaha, but play were you are best at if your goal is for money, I prefer omaha, actualy omaha hi low is my favorit game, but im much better at hold em, omaha hi lo way to much to keep straight
