>> should be rare-ish
it should be reserved for awful matchups like sheik vs cf. i just dont see falco owning cf like sheik, and not even close to it really. The basic idea is sheik grabs falcon hes screwed. if falcon approaches sheik nair and ftilt BEAT EVERYTHING. then you add a projectile advantage, and some very easy gimps and that rounds it all up to 70-30 or so. Falco really only has the projectile advantage hes not even close to tech chase gay (i dont even think good shine combos compare really). falco gimp falcon like everyone else, but not NEARLY as bad as sheik can. nairs, ledged bairs, dsmash spam (sometimes, its hilarious though) needles to mess with low recovering falcons, and well placed fair can end it too.
I just don't see it
I second sheik >> samus. sheik can deter projectile spam incredibly well (lol 1 needle vs full charged shot). there seems to only really be two ways samus can kill sheik as well. the first is edgeguarding, which most characters can do to each other anyways. the second is a fsmash, which sort of lacks diversity. AND sheik can pop samus' bombs if she can connect her needles with a recovering samus, which seriously impairs one of samus' greatest strengths.
