Shanks's bounty: 4.048 B
Big Mom's bounty: 4.388 B
Kaido's bounty: 4.611 B
Whitebeard's bounty: 5.046 B
Luffy's bounty: 3 B
Buggy's bounty: 3.189 B
Teach's bounty: 3.998 B
Notice something? The OG Yonko are in the 4B bounty range, with WB even reaching 5B due to him being PK level. However, the 3 New Yonko are stuck in the 3B range. The reason for this is that the world does not view these 3 as being on the same level as the OG Yonko. Ask yourself why Oda chose to put Teach's bounty so extremely close to 4B instead of just giving him a flat 4B? It's because Oda wants to tell us that Teach hasn't reach that level yet, but he's almost there. The Yonko are simply just the captains of the 4 strongest pirate crews. They don't all have to be on the same level. If Teach and Luffy both died suddenly, Law and Katakuri would replace them as Yonko despite not being anywhere near as strong
