Do players have natural games?

I have been playing on-line for 3 months or so, hold-em and Omaha 8/b. Admittedly, the samples for both games are small, but I think I have a better "feel" for Omaha 8/b. I seem to have better hand selection pre-flop, and believe I quit more marginal hands post flop than at hold-em. Am I just fooling myself?
