What if I said his movement seems to have the most potential, but isn't necessarily utilized in the most efficient way? I definitely can see that in the spacie's matchups in particular. I guess my definition of "best" is flawed.

Aside from what ace said, I see a good amount of holes in your neutral game. You're too fast to shield, even after you cc a laser. When you have the space and falco has committed to a sh aerial approach following a laser or you're close by him straight after a laser, cc jab is the way to go. If you shield preemptively, you're playing into his hands.
I see you have shield drops down pretty well, something apparently only a few Ganons can do kappa. But you have the same problem I used to have and still do to some extent: you're predictable with em. You almost always went for shield drop uair. That's one of the best things you can do out of shield drop, but it's not always safe. Try mixing up what you do oos on platforms. Rising sh dair can be good. Wd off works too sometimes. And shield drop wl can give you some good spacial advantages.
You have a bad habit of side-bing too much. You probably know. Sometimes it was pretty good, like when you do it in the opposite direction after a jab.
For DI, try to DI behind falco off shines more. It's harder for him to followup.
Finally, try to find more uses for dash attack. It's really good vs. falco, and the one or two times you did it it worked. In fact, I'd say try to replace your desperate side-bs with dash attacks when falco is close by just as a way of experimenting with what situations it works in.
