There is another pattern as well imo. Benn, King and Katakuri are the RHMs of the current 4B+ Yonko. Marco and Rayleigh are retired, Blackbeard will be stronger than the emperors soon but not yet, Sabo is a revolutionary, Killer and Bepo are upcomers.
So if you just focus on the part with Benn, King and Katakuri - you see that Benn is angled to the right, King stares straight down and Katakuri is angled to the left.
And in the middle of the trio? Zoro - the RHM of the guy who is aiming to surpass all three of the 4B+ Yonkos by the end of this arc.
Benn > King > Katakuri

Btw I know you are bias, the good news is I'm not bias like some other certain users or else there would be a back and forth argument on who is stronger between King and Katakuri lol.
