User blog comment:Black Leg Sanji/Scale 1-10: The Marines Scared of Certain Crews/@comment-3119203-20101117014858

The blackbeard pirates have five famous convicts, a former shicibukai, and several other powerful members, so they are around a 9 (remember that the gorusei considered him as a yonkou), the straw hats can be beaten pretty easily by an admiral before the timeskip, so then it was a 6, but after its hard to tell. The whitebeard pirates are definitely a 10 before the war (the marines summoned all their forces to battle), but afterwards they lost a lot of strength, and the red-haired pirates are a 10 as well, judging by the fact that 1.the marines didnt want to fight him, 2.Shanks is a yonkou and 3.Shanks could fight Whitebeard on equal terms
