Technically, Ganon's fastest ground move is grab, which comes out in 7 frames. It's still so unfortunate though, how slow Ganon's jab is .For once I believe Ike can safely say he's the *slightly* faster character in this match. Jab comes out twice as fast as Ganondorf's fastest move, and almost three times as fast as Ganon's fastest ground move (3 vs 8).
The match-up is definitely in Ike's favor, although I don't know exactly how much; Ike's FAir can pretty much shut out anything Ganon has, but if it whiffs then you guys might be able to side+B or down+B us during landing lag if you time it right. The same may be true for BAir.
In close combat, Ike definitely has the upper hand; his jab comes out in 3 frames, twice as fast as your fastest ground move (grab, which comes out in 7). In addition to dealing damage, can also set up for some nasty things like jab -> grab, jab -> UTilt, or jab -> BAir (all dependent on DI).
Edgeguarding is more even; Ganon can either side+B (which is easily spiked by DTilt or DAir) or up+B, which is probably the safer option. However, Ike can walk-off DAir spike the up+B or edgehog; even if you land on the stage, Ike can edgehop back onto the stage and then proceed to punish from there. Ganon, on the other hand, does not have as many options when edgeguarding Ike; side+B is a laughable recovery that good Ikes will only use when you're not around (and it's really easy to gimp with DAir, jumping out and taking the hit, or with an edgehog), but Aether is a reasonably safe recovery move. The easiest option Ganon has is to edgehog it, but jumping out with reverse UAirs will work as well; just be wary of the Aethercide if the Ike is ahead.
