You have brought up pretty good points in your defense. But I have to disagree.
- Amatersu was repelled the flames bu using a highly advanced technique, which is in a league of its own. Heavenly rotation basically scatters physical objects away from the user. it can be noted it Neji's fight against Naruto, and during Sasuke's chase. Amatersu flames do not possess any physical form, so I cannot see this technique countering Amatersu.
- Susano is not a human being, nor does it have chakra flow points. It's basically a manifestation of Ms and EMS users chakra after acquiring the abilities Amatersu and Tsukoyomi. I can't see any Hyuuga breaking it apart.
- Sasuke has fought much faster opponents and dodged their attacks with his three tomoe Sharingen. As Ms or EMS don't predict moves any better nor do they enhance it, I also cannot see Neji - being an elite Hyuuga - taking this. As not only three tomoe Sasuke is much faster, which is one of the key factors of dodging attacks and launching offensive attacks, he seems quite good at hand to hand combat. He can also read Neji's moves perfectly.
- Chidori is basically a lightening technique, how can the rotation technique deflect current? I can't see Neji dodging variations of it as well, such as Kirin.
- The last point seems somewhat valid. But given the rest of explanation, I can't see Hyuugas beating a three tomoe Sharingen user. It will be a one-sided match.
Great post regardless.
