H2H. I have made this comment here a few times b4 and will do it again. In H2h it is so much more like real baseball. You have teams playing each other and the top teams make the playoffs where anything can happen. I have never seen a world series determined by which team had the Highest batting average, Most stolen bases and most Hr's. It is just not as realistic as H2h.
There will come a day when Barry Bonds leaves baseball, and everything about the game will be the better for it.
