Are we really saying she can deal with a 10x speed gap, (with AOE too, let's not forget that) because she's skilled? While ignoring Sam humiliates dudes who are like two dozen skill ***** above where the worst of the worst have an analytical prediction bordering on precog (Including some who actually
do have precog), enhanced senses, the ability to copy shit at a glance, know what the foe will do before they do it based on minute movements like muscle twitching/changes in the atmosphere/r just out predicting, and have mastery in who knows how many martial arts, including one that was considered so far above any other fighting style that like 50 years after it was invented it was considered cutting edge and beyond any other martial form (And that was just a shit imitation of it, that was actively so insulting that Snake subconsciously started to use the real thing out of spite).
She isn't dealing with a mook with a 10x speed gap, she's dealing with a dude who like hyper upscales above skill gods. Hell in MGR a literal supercomputer that can analyze and decide the best course of action, analyze something to find weakpoints, and the best place to attack is a joke.
He may not consciously use it differently but having a blade that cuts through anything else is going to inherently mean there is an unconscious difference in how he uses it.
Actually, in context of the verse, most of the shit he uses it on
resist the effect (Like, other HF blades, so basically every sword duel he'd ever get into, or cyborgs to an extent, aka every foe he'd get into a fight with, etc), so to him, he's just swinging it like it's a normal ******* sword, maybe a sword beam here and there if he gets thrifty.
