Using Ganon, I have to accept that Ganon's recovery IS one of the worst in the game, I unavoidably get gimped so often with him it is definitely about as bad as Link's, and because of its terrible horizontal distance, good DI and saving the double jump is often required with Ganon, and even then he still gets gimped. His Uair often prevents unsafe rushings of the opponent but doesn't help so much that he can't get gimped. You can hit through his Up b during the start-up or hitting directly above it, and like Nidtendofreak said you can punished for grabbing with Up b by a large cast, depending on their aerials it may lead to a gimp or not, though most of the time you don't even need that at all to gimp Ganon so easily. And the 30 frame landing lag from grabbing with Up b complicates getting back to the stage with Ganon, and to get back with ledge dropping he is required to use ledge drop + double jump and air dodge immediately after that is pretty hard to do. Despite how bad his recovery is, Ganon can surprisingly still gimp really well with Uair, Nair (against other bad recoveries) and with an occasional Dair, though his short horizontal recovery prevents him from going too far offstage.
