mihawk said settling things,
No one win.
If you think mihawk was really thinking Post-Yonko Shanks didn't get stronger, and thinks that Shanks, who rivals Kaido and WB, isn't worthy of fighting, but Don Krieg, Vista and Pre-TS Luffy is?
You are dreaming. The fact is that mihawk knows Shanks is stronger, he is making up excuses, just like he admitted the difference between himself and WB.
Shanks would never say that;
He rivals WB, Kaido.
While mihawk rivals Vista.
I don't care about how he got stronger after losing arm, the point is you don't become a Yonko without getting stronger. Shanks wasn't a Yonko when he had 2 arms, after losing his arm, in 6 years he become a Yonko.
