Anyway, from what's being said about Zoom, he is certainly impressive (especially if he's never, ever been struck in combat, which then raises the question of how much punishment he could actually take). But he doesn't have the power or versatility of the Surfer...and off-hand, I find it difficult to accept that Zoom's sheer advantage in one area -- speed -- would be enough to compensate. I'm not as familiar with Zoom as I am with the Surfer, so while my opinion remains unchanged (for now, at least), you've definitely given my things to consider.
Galactus>>zoom
That's pretty darn fast, indeed. Let me take it from this angle: has Zoom ever been defeated in combat? If so, by whom, and using what approach? You mention that Zoom was...
I don't remember him getting beaten
What were the circumstances, and why couldn't the Surfer do this?
Zoom was taking on the JLA/ Superman, Hal, WW..etc. Hal caught him, but he broke through easily.
PIS is a thorny issue -- not that it doesn't exist, but it is a somewhat subjective call (lord knows, I've had to defend the Surfer numerous times using the PIS card). In any event, again, I'm curious as to the circumstances.
PIS sometimes does apply. CIS also too.
Zoom has many chances to kill Wally...etc. He never did. That's PIS imo. Galactus losing to earth was PIS(imo)
