See, this would be the easiest damn take on the planet. Imu isn't a swordsman, nothing he does reflects on Mihawk whatsoever.
But apparently this take is worthy of being mocked in the opinion of a bloke that wants to have his cake and eat it.
Naw mate, Imu is a sword holder but not a swordsman so he somehow upscales Mihawk without invalidating the only hype he really has (WSS) and Mihawk would beat Imu in an arbitrary scenario that would never happen where you strip Imu of most of his arsenal including his predominantly not-a-sword sword that makes him a not a swordsman sword holder.
Clearly the more logical take.
