Darth Maul vs Anakin

It was his first go with Vaapad channeling, what's to say he can't refine that to the point where he can channel ****ing everything and be Sidious tier? He's Obviously not as powerful as someone like Sidious, Revan etc. but he takes that power and uses it to himself much like Vitiate doing bullshit rituals to make himself almost God. So he's not as powerful as the top Sith Lords with his own power, but everytime he comes up against one what's to say he can't beat them as he's already stated to be an equal of ROTS Sidious with channeling on his test run

He can reflect a Sith Lord's own power back on them assuming he needs to. He's already more powerful than Maul so wouldn't need to in his case. And he's already equally powerful to Dooku so again there may be no major advantage in that scenario either.

But when he's fighting equally, Shatterpoint seems to give him the advantage.

So yeah he'd probably take almost all other Sith Lords including Vitatie.

Mace getting KO'ed by a missle has little bearing on his ability in lightsaber combat tbh but I would agree that Sheev seems quite a bit better a combatant than Windu overall.

That's a dangerous no-limits fallacy imo. Combatants have different strengths and weaknesses. Saying Mace has an auto-win is silly. He couldn't beat Dooku. Theres also no proof that he could replicate the fight if someone were to use something other than lightning, like sorcery, telepathy or tk.

With all of Mace's inner darkness I only think it'd be easier for Vitiate to dominate him like he did Revan and Malak, personally.

I suppose by bringing up Vitiate I'm skipping around between Canon and Legends, where I was originally just speculating on Vapaad in Canon.

Dooku hasn't stalemated or beaten Mace in Canon.

Canon's weird though. Jedi can get sudden unexplained amps like Kanan against Maul, and Rey against Kylo Ren. So there's various ways Mace could have been amped against Palpatine as a one off. So he'd need more showings to prove he's consistently on Sidious's level. Because so far, his other showings are not displaying that IMO.

But then given Lucas himself said Mace can compete against Sidious, Vapaad's still the most plausible explanation.

I don't think anyone believes that Mace is naturally a rival of Sidious.

In Canon, it's possible.

Canon includes the RotS novel.

Nope nope.
