Still think mewtwo should be killing at percentages he can die at. Otherwise Ganon does fundamentally everything better. Custom Ganon anyway.
Can he make a long distance punish or reflect the projectiles that give him so much trouble? Can he pester people
when he's not in range? Saying he does everything Mewtwo does but better is kind of a stretch. He plays the PUNISH
game better to be sure, but it comes at the cost of a less solid neutral than Mewtwo's.
Here's what I see Ganon having over Mewtwo:
-Kill power
-Vertical survivability
-Longer command grab that can kamikaze
-More threatening anti-juggle attacks
And here's what Mewtwo has:
-Projectile (good for harassment and killing)
-Reflector
-Faster footsies
-Mobility (not only are the natural specs better but he has much more options like confusion jumping and shadow ball recoil).
-Grab game (it may be short but it beats Ganon, and it doesn't lag terribly either. And Ganon may get guaranteed stuff at low
percent, but Mewtwo can outright kill pretty easily and even just creating space is good when you have a projectile).
-Recovery (dropkick does close the gap significantly, but it still doesn't quite match the mixup potential of Mewtwo's).
-Edge guarding (Ganon is lethal, but Mewtwo can actually go deep where the discrepancy in power becomes somewhat moot).
-A minor thing, but lightweight + floaty breaks some combos.
So while Ganon has Mewtwo beat in raw lethality and survivability (with customs), Mewtwo is much more flexible
in how he goes about his game and can never be counted out in neutral with relatively fast footsies, projectile and reflector.
