What makes you think Saint Shanks wanted to be strongest swordsman?
As I said, Mihawk is superior to Saint Shanks, canonically, only in sword skills.
Saint Shanks on the other side is an emperor, feared by the Marines and untouchable, and has a higher bounty.
Which makes him superior to Mihawk on a variety of fields.
Why does it matter what Saint Shanks wanted?
Is WSS something Mihawk wanted, or just what he is? It's not even the same comparison, because Saint Shanks isn't Pirate King while Mihawk IS the WSS.
We are explicitly told that Saint Shanks was Mihawk's biggest rival and both the World Government and Whitebeard have knowledge of this, yet they still believe Mihawk is the strongest swordsman.
The original post I quoted was trying to imply that Mihawk is a "failed rival" of the Yonko just like Crocodile and Moria, lmfao. I don't care what other accolades Saint Shanks has. Mihawk is obviously the outlier of the Warlords, as indicated by his Yonko-level bounty as a "subordinate" while no other OG Warlord has even cracked 2Bil
