Heres mine I also prefer to use the marine ranking level + yonkou, PK, and God Tier
God Tier: Anyone who could beat Roger.
Joyboy: This guy was the king of the AK idk I just think he could beat Roger in a fight for some reason.
All Gorosei together: All 5 together will be immensly strong and probably Luffys final opponents.
EoS Luffy: He's the MC so its pretty obvious he will surpass Roger.
PK Tier: Anyone who can med diff a Marine Admiral
Roger: Obvious
Prime WB: He was only slightly weaker than Roger.
Garp: Same with WB, but the gap between him and Roger was a little bigger.
In between PK and yonkou level is Dragon.
Yonkou level: Anyone who can beat a FA level fighter but not a PK level fighter
All 4 yonkou: Obvious
An individual Gorosei in their prime: A guess.
Shiki: Obvious
Prime Sengoku: Obvious
Mihawk: Rivals Shanks
Prime Rayleigh:First Mate of a PK.
Fleet Admiral Level: Anyone between yonkou and admiral level
Post-TS Akainu: He is stronger than all admirals but weaker than a yonkou.
High Admiral level: Slightly stronger than your average admiral.
Pre TS Akainu: Obvious
Aokiji: Obvious
Med Admiral level: Your average admiral
All current admirals: Obvious
Yonkou first mates: Marco fought on par with Kizaru, Beckman could apparently fight on par with Kizaru, Shiryuu was Top VA level Pre TS and then has been in the the NW for 2 years. Other 2 are just because of hype.
Sabo: Is not going to get med diffed by Issho like people say, if the fight were to conclude Issho would win high diff.
Old Rayleigh:Fought equally with Kizaru.
Low admiral level: Could become an admiral if they were in the Marines, but would be lower than average for an admiral.
Doflamingo: Stronger than everyone who is Top VA level.
Kuma with a brain: OP DF.
Top VA level: Strongest of the VAs
Buster Call VAs(except Yamakiji): They performed the best at MF. They are Momonga, Doberman, Strawberry, and Onigumo.
Dalmation: One of the best VAs at MF.
Luffy: Can beat everyone in this level but not Doflamingo from current feats.
Vergo: Mid diffed Smoker, if not low diff.
Zoro: Can beat Sanji and Smoker, I can see him beating Vergo high diff.
Magellan: Very OP DF.
Law: Very close to Luffy.
Kidd: Same with Law.
X Drake: One of Kaido's high ranking officers.
High VA level: Beats mid VA level opponents.
Smoker: More impressive than most VAs.
Yamakiji: Hype
Hancock: Obvious
2 more VAs: I believe that every VA level has 5 of the 20 VAs.
Sanji: Can definitely beat any Mid VA level fighter, very close to Top VA level.
John Giant: Seems to be the strongest of the VA Giants.
Jinbe:I can see Luffy and Zoro beating him, and maybe Sanji can extreme diff.
Hawkins: One of the middle level Supernovas.
Apoo: Seems to be as strong as Hawkins.
Killer: Is the Zoro of the Kidd Pirates but lacks feats
Med VA level: Your average VA.
Enel: His strongest attack can destroy small islands, only lost at Skypiea because his attacks dont work on Luffy since he is rubber.
Bartolomeo: Low diffed Maynard.
5 more VAs: Mentioned why above.
Cavendish: Could probably low diff Maynard like Bart.
Franky: His General Form has been very impressive.
Robin: Probably close to Frankys level.
Pre TS Croc:Low diffed Luffy 2 times and only lost the 3rd time because of plot.
Capone: Spent 2 years in the NW
Bonney: Same as Capone
Urouge: Same as Capone.
Low VA level: Weakest VAs.
Maynard: Nuff said.
Brook: Weakest of the SH's Mid Trio
Pacifistas: Got in between mid and high diffed in a fight against all Pre TS Straw Hats. One shotted by Post TS Luffy.
4 more VAs: Mentioned why before.
In between are Pre TS Luffy and Lucci.
