Yonko vs. Admirals is a really stupid debate imo. Not every Yonko or Admiral is set to a static power-level, there is potential for gaps even if there is theoretically a threshold of power you need to reach in order to gain either status (even though Buggy technically debunked that for the Yonko, but whatever). If you're saying "Yonko > Admirals" then that implies that someone like Buggy is stronger than the admirals. Prior to Buggy, I'd say the Yonko had a higher average PL because of people like Kaido, the World's Strongest Creature, in addition to Shanks and Blackbeard being endgame material. At the same time, the Yonko side also has Big Mom whose showings are not great...and I think there is the possibility that every admiral is stronger than her honestly.
