At this point in the story, Admiral vs Yonko is a difficult if not pointless debate.
It's basically the One Piece equivalent of Goku vs Superman. As in, it's a discussion that sounds fruitful in theory, but in actual practice there's just a lot of nonsense going around because both sides are very differently written and honestly hard to compare.
The only proper drawn out Yonko v Admiral fight we've got was mostly offscreen, involving an Emperor with a time limit and an Admiral with crippling depression, both limited by the fact that they were trying not to destroy the island they're on.
I don't like to fully compare them rn. Maybe on small individual aspects, maybe some speculation on EOS rankings, but giving definitive opinions right now seems silly to me.
