Sidious, even as of ROTS, just packs a greater punch in combat. More Potent lightning and TK. Vitiate is capable of holding him off if it comes down to a battle similar to Sidious vs Talzin, as NewGuy said, but Palpatine will overpower him. However, if Sidious manages to close the distance fast enough (we all know how fast his is), Vitiate doesn't stand a chance.
@Sinious, I didn't say all Vitiate's quotes were hyperbolic, but quotes such as, "Godly" and "lightning infinitely greater than Nyriss's" are hyperbolic; not to mention the lightning quote came from Revan, referring to a nexus amped Vitiate. Sidious's quote from the DE endnote is literal, and it beats even Vitiate's exaggerated quotes.

Oh well obviously he is not a god and I think the word infinity is just used to depict how much more powerful Vitiate was compared to any other sith of his era and even for Revan, he was too much. Nobody, not even the Ones of Mortis has infinite power. But I get what you mean.
Yes, I agree that DE Sidious is above Vitiate in that regard but imo, if any other sith comes close to DE Sidious regarding force powers, its the Sith Emperor.

Team 1 soundly. Sidious is the greatest with of all time and vader is most likely better than revan especially by this time, then star killer is definitely more powerful than malgus. So with that team 1 takes this competition easily.
