Mace Windu (OCW) vs. ROTS Darth Sidious

Why not?

Windu also has his Vaapad amp.

Force, sabers, all out

Battle takes place on neutral ground

*Starting distance 20 feet

Stalemate

Sidious

Windu wins on feats.

Which is why feats are such an "Objective" measurement.

They stalemate for a while then Sidious throws the duel in order to manipulate Anakin to the dark side who kills Mace and then slaughters everyone in the Jedi Temple

It was clear Sidious' lightning would have overwhelmed Mace, if nothing else.

The Emperor.

No matter how bad azz he iz zidiouz win....
