1. I think you came to the conclusion that CoA=hardening which Oda created during the timeskip. CoA=invisible shield and hardening, both falls into that category. So, still no.
2. never even said CoO
3. lol what? he has haki yet he can't coat in CoA? doesn't make sense bro. Look at #1
4. Hakified slash=cutting dmg>blunt dmg
5. Im talking about luffy in this case, not sanji. He cocks his hand back and releases it. It does more damage than a normal punch
6. look above and thus extreme diff if you didn't see that part. Also I think both smoker and Sanji would lose to vergo so I have no idea why you brought them up.
I already regret that I replied to the last post.
1) well duhh, I think you finally came to the conclusion what I was talking about when I spelled it out for you.
2) Just stating the difference for you to understand point 1 but it failed.
3) There is no prove, it are two different things under the same name. It's like saying I can do a karate chop that makes me a karate master and do all the karate moves. (NOT SAYING THAT ZORO CAN'T, BUT HE SIMPLY HASN'T DONE IT YET)
4) We were talking about Luffy here as an 'physical fighter' I already made a difference between cutting techniques, go read it again. It will be a long ass fight if Luffy will fight hand to hand with Vergo.
6) Never said that Sanji or Smoker could win against Vergo just brought them up to clear up point 5, hand to hand combat is Vergo's strength. Sanji and Smoker are strong enough as a benchmark to predict that Luffy will have a hard time versus this guy.
One other thing if you think that Smoker and Sanji lose against Vergo who also both have CoA, do you really believe Zoro would do that much better and beat him ? Doubtful.
