You keep coming back to the multi attacks;
1.Nero can dodge attacks that have multiple hits (see: YT video)
2.Nero can also do these attacks - RQ+yamato+summoned swords+BR
And you're neglecting max act; Nero is quite sluggish at swinging his sword compared to others, but exceed greatly increases his attack speed.
Again, I think Nero would lose this fight, but I don't see it being a one sided curb stomp like you seem to.
