I say RM2K/3 just because everyone uses XP. Now, with that being said, if you find XP more enjoyable, use that. I am using XP, even though I have RM2K/3. I just find XP easier, with the kit and all. I guess it comes down to whether you want to script or event more, since 2K is so event based for everything. Come to think of it, forget my vote. Go with whichever you enjoy more. That is what my team keeps telling me.
