Hyouzou > most of Flying 6 tbh.
I don't think They realize that Flying Six were comparable to "Subordinate" Enemies we've seen in Pre-TS,
Black Maria for example is comparable to Boa Sisters, who were both Defeated by Pre-TS Gear 2 in a 1v2, Hyouzou wd Delete her.
The Idea isn't that Yonko have Subordinates stronger than what we've seen before or Pre-TS, the Idea is that Yonko are so Great that They can have multiple Commanders like those, but since most Readers praise the new & forget the old, They end up underrating/overrating almost everyone.
