Got a Real World Weapons or Armour Question? Mk XI

[Conners]

With some of the largest swords and weapons out there, which can actually and have actually been used in war: Would a supernatural level of strength be very beneficial in wielding them?

I've been trying to consider the effects of a character with unreal levels of strength, and how it'd play out in a manner of realistic science-fiction. At a certain level, no matter how strong you are, the weight of the weapon vs. your own, the leverage you have over it, and perhaps some other details will get in the way of wielding absurdly large weapons--and, I suppose, they would also get in the way of wielding a odachi with the speed and ease of a plastic toy.
