Its not my opinion, caps lock typing little bro. Every time Oda shown shanks display, he didnt say Swordsmanship, he said haki
This include the scene where he 1:1 clashed with whitebeard like Harald and Rocks this chapter. You will find in that chapter "his haki is amazing as ever" not 1 word of "swordsmanship"
Wanne see the kanji?
Your headcanon doesnt matter here, defintive proof that being a better swordsman is not associated with having better and more haki.
Until you can disprove it with manga pages, your headcanon deostn amtter to me

This isn't a point.
Oda has outright called advanced haki on a sword = swordsmanship
Shanks haki has been hyped when he's done base coc
Why would they talk about his swordsmanship then moron
And what if he splits the skies with mihawk when see that flashback does that not count since its already been called a duel now ?
