@Dan:
Assuming Rayleigh is strictly a swordsman, which i doubt. He seems much more likely to supplement his overall style with the a sword much like WB did with his Bisento or Lucky Roo and Beckmen likely do with their guns.
Considering he doesn't have a DF and chose to fight Kizaru with his swords, I doubt that.

**Can't be bothered to link you to the exact pages right now, but here are a few examples:
-Akainu told Jimbei that being a Schichbukai, he should be well aware of the power the Admiral wields. Jimbei said something to the effect of "If by tearing this body apart, I can delay you in the slightest then I am content." That's clearly Jimbei admitting he's inferior to Akainu.
-He couldn't do anything to Akainu at all in the war, the only thing he could do was run away with Luffy.
-Ivankov whom seems around Jimbei's level or stronger imo, was basically one-shotted by Akainu.
