Killingham and Sommers are regen merchants that cannot hope to even bring out 50% of power of either Sanjinor Zoro.
Beating them does not prove that you can match rooftop Zoro's performance. A superior performance isnt needed against those two, they are neither capable of something like Hakai nor are they as tough as Kaido...
Sanji will enjoy the narrative equality that all aCoC users share but the pecking order still exists.
The world's strongest people exist. Number 7 and number 1 cannot be equal even if narrative says they are shoulder to shoulder...
Zoro's narrative purpose is defeated is anyone is equal to him, he aint striving to be anyone's equal... Let's not delude ourselves here.
Sanjino can be super strong without being equal to Zoro. Stronger than Luffy should be more than any Sanji fan could have ever dared to dream about.
Non-swordsmen simply cannot dream about matching the swordsmen.
Even tho, Garp has proven that punching holes in people is all about overpowering their haki and whatever defenses they might have on top.
And after seeing Luffy's punches with acoc doing nothing significant, it becomes clear why Sanji neither will fare better there.
I want the same stuff you are smoking.
