I have yet to see a scene where an admiral ever looked superior to a yonko
Damn you have yet to see a scene? Here you go, free of charge.
I believe there are objectively more moments in this manga where Admirals are looking superior to a Yonkou.
For Yonkou > Admiral moments on panel I can think of Shanks against Greenbull, Luffy turning depressed Kizaru into a pizza? And I guess Shanks stopping Akainu?? That's if you reaaally wanna stretch it.
I can't think of anything else. WB cheapshotting Akainu from behind? Nah cause Akainu also punched his head off, so I didn't include that, as it's a wash in the best case scenario for the Yonkou.
I don't believe I'm missing anything else. The rest are either washes or not direct interactions.
