>Bad swordsmanship skills

I guess that's why he became the strongest member of SOLDIER and the inspiration for all future members.

Masamune is comparable to a Devil Arm in that it is not a regular old blade, and it's capable of combining with materia, making it just as strong as most weapons from DMC. As you said in this blog, Yamato struggles in destroying Devil Arms.

You completely disregarded both of Sephiroth's super forms, Bizarro and Safer, which completely trump anything Vergil has. Even in base, Sephiroth is stronger and faster than Zack Fair and Bahamut Fury, who are both able of casually wiping the floor with the DMC-verse, being Star level.

Vergil is Continent level at most by scaling to Composite Dante.

Case in point, you should have done more research.
