It's been 2021 following one piece for more than a decades that's why we know very well the structure of how Oda sets up.
Tobbi roppo are never as hype as the Calamity, especially King is given more love and respect by Oda among any other BP from the start of Wano, he make Queen who's just below him (in terms of rank) look like a whimp. Just by this structure, King follows the same pattern of giving more hype of being a YC1 by Oda
All tobbi roppo who got 1v1 by Strawhat get beaten under 2 chapter. King vs Zoro is already 3+ chapter and King hasn't been in his hybrid (just partial form). And even get slight advantages over Zoro in this chap.
So anyone with brain can tell this is going to end at least in a close fight.
