It's doesn't surprise me at all that this discussion evolves to some general WR discussion. The games differ too much to be compared on such insane levels as WR's, but if you really have to, I always look at it this way:
GE is like checkers, its simple as hell and therefor insane in a way that you can optimize much better.
PD is like chess, its (more) complicated on its own, and therefor impossible to be executed at the same level of "insaneness" as GE.
it's really easy to think ahead a couple of moves on checkers, there aren't that many options after all. If you look at Chess, the whole tree of possibilities gets so huge after only 2 or 3 moves, it's nearly impossible to match your skills in checkers.
