So basically what you're saying is ganon has to start everything out of a read but for some reason Falcon can't.
As Alph said Falcon has hard read options too, not only in his dsmash, but also fsmash.
Falcon's Upair is just as good as Ganon's and he can actually upair us from a grab release and begin to string, Falcon's Bair is just as good as Ganon's and will kill you almost anytime Ganon's will. And if your getting hit by Dair please start using upb.
Falcon's u-tilt can clank with our fsmash and dtilt. Falcon's Fair is wayyyyy better than Ganon's. Falcon also has a usable frame advantage out of throws.
For real any time your getting hit hard by Ganon not only should you not be, but Falcon also has the opportunity to hit just as hard. However, Falcon actually has options (although not good options) from a neutral position unlike Ganon.
The only thing that Ganon has is his Side B tech chases, which you should not get hit by Side B and if you do, guess what, you can still avoid getting punished.
