They never said Shanks commanders have the highest bounties
Just that, his crew boast high average bounty... balanced crew
No Yonko underling has superior bounty than Luffy. Or else he wouldnt be hyped 5th emperor.
Marco (became Captain for one year, fouhht 2 wars even tho he lost ) will not have higher bounty than Queen/king still... coz calamities are more brutal, Kaido lets them roam and do whatever they like outside or inside another.
SCs do not go rampaging countries or trotting peopl, BM sends Tamago, Randolph for those tasks that's why you see Tamago has higher bounty than Oven despite being weaker. BM sons stay at home usually.
WB pirates arent savages either
Shanks care isnt savage also depsite Yassop Roo Benn being famous.
Do people forget Yassop was a famous Sniper before joining Shanjs ? Benn probably was also a famous dude before joining shanks. Unlike Marco Jozu who were teens when they joined WB , they made their names under WB. Unlike Kata Smoothie ... who are BM children, they werent famous outside BM name.
My guesses :
I believe king has the highest bounty among all cammanders
King 1 330 000 000 (he and Queen are like Zoro and Sanji)
Queen 1 320 000 000
Benn 1 280 000 000
*Marco 1 110 000 000*
Roo 1 088 000 000
Katakuri 1 057 000 000 ~ symbolic for Luffy
Jack 1 000 000 000
*Marco 980 000 000*
Yassop 960 000 000
Smoothie 932 000 000
Jozu 880 000 000
