You Bastard

Hi, everyone. I'm new here to the forum. First, I have a copy of the original Guilty Gear X2: The Midnight Carnival, and its Slash revision. In a university I go to in New Zealand, there was an arcade machine containing the original Guilty Gear X2: The Midnight Carnival. Now, it contains its respective #Reload revision. I should probably get to a stupid query, so here it is: Since I can't find a copy of the PS2 port of the #Reload revision, which version of X2 I have is closest to #Reload, in terms of game-play mechanics and character balance changes?
