funny because to prime roger they are about the same
They are clearly strongest marines
But if we go by equal logic then roger = wb = garp = sengoku
Everybody is not equal and its pretty clear that no matter how close the gap would be garp is still over sengoku
Oda portrays it that way, same can be said for alot of other duos in the story
Akainu and aokiji could be called equals but akainu still won, oda showing his portrayal as stronger during marineford proved to be true, no matter how close the fight was
Same could be said for kaido and big mom. Kaidos portrayal is superior but there's also alot of evidence to pair them together like sky split and 3 day fight
