You know equality isn't level.
Everyone thinks no Admiral is equal and no Yonko is equal. A Yonko level is more or less just stating that all Yonkos will need high+ diff to beat each other lol
I still don't believe in those levels
I think all of them are considered simply "Top Tiers" and thus making them able to confront each other
Whoever wins doesn't mainly mean they are strongest
Many factors come into play like DF match ups and most importantly PLOT and reason behind their fight...
For example
I knew immediately that once Jinbe said Akainu vs Aokiji happened.... before I see the next scene that Akainu won before he says it... plot demands that whoever is on top of Navy must be ruthless against Luffy.. as simple as that
Let's say Luffy somehow comes at EoS and his main enemy is Imu sama
and Sabo somehow is occupied or more focused on another enemy in that war...
And Aokiji steps in to help Luffy and co and he has a score to settle with Akainu... and he turns out to be Akainu's final match in series... then PLOT simply tells you Aokiji will win... VERY EASY to guess
That's what I mean by my words
