Hybrid has never been much of a power-up, I told y'all but the Kaido fanboys were trying to hype up his new form saying he would offscreen the SNs with it for some reasons.
Base Lucci >> Base Luffy
yet
G2 Luffy > Hybrid Lucci
Whenenver a zoan went hybrid we never saw much of a difference in power, it is a minor boost at best, and only for specific fruits.
Animal form can be > hybrid for certain fruits, it depends on which is more useful/suited to the situation
Zoan Kaido is an easy target, not very mobile and easy to maneuver around but it has the highest DC+AP+Durability of all his forms I stand by that, he just never manages to land hits because plot.
As for King, his Base and Zoan are of equal threat, his hybrid is only used to make slashes.
