That seems a little biased as well. There was no acknowledgement of Bon or Wanze, and besides the principles of spinning and using fire, the technique is complete different. Sanji contains heat in his legs through his shoes, while Wanze just ignited a spark. And even if it was from the fire skates, that doesn't make his "stealing" any different than Zoro's. Despite the fact that Zoro always names his moves after animals and mythical creatures, and was clearly inspired by Asura and not Robin.
Whatever it was inspired by, i don't think there's anyone who would disagree that the Asura technique would be more inline with a robin ability over a Zoro ability, whipping two extra sets of arms and legs out of nowhere is incredibly cheap. And while you doubt the origin of Sanji's technique it's actually quite feasable, especially given that techniques like the __ pound cannon were just whipped out of nowhere without ever being demonstrated. I don't think it is that much of a stretch to say that Sanji adapted the techniques of Wanze and Bon Clay and combined them, especially when we've seen Luffy adapt Croc's storm, Blueno's soru and other characters adapt other moods right before our eyes.
Oh, and though Zoro said a bunch of swords doesn't make you better, he meant in effect. Not sure how to phrase it, but what he meant was that just having them wouldn't make Hachi better than him. Else he'd be a hypocrite, since he was originally a two sword fighter.
You're right, Zoro is a hypocrite, but he learn't the hard that that just because he had more swords it didn't mean he was a better fighter, it was about being a better fighting using the techniques of those swords and so he's kinda allowed to be a hyporcrite.
Even up until that point. Like I said, unless it ends in a double KO, it wasn't even. A small margin is what allows someone to win, and until both have shown their best, you can't really say that.
We agree, it was Oda's writing over Zoro's ability to tip the scales. though to be honest, i'd say settle for saying that Kaku's swords weakened him. Either way they were EVEN up UNTIL a certain point.
