Ehh, not really no. The nexus didnt change the fact that he was still weakened. In fact:
"You’ve learned that the Emperor is on Dromund Kaas, temporarily weakened by your efforts thwarting his plan for galactic annihilation. Striking at him now is your best chance to defeat him once and for all. While your other companions risk their lives to draw off the Imperial forces, you and T7 need to confront the Emperor himself."
-this is the mission description to enter Vitiate's chambers, so he was still weakened, regardless of the temple.

Moving a tank>Opening a door. Also his Clone Wars feats eclipse the Barsen'thor. Also the Barsen'thor has absolutely zero saber feats to suggest he'd last more than 5 seconds against Mace.
Vitiate being weakened doesn't mean that he is weak. And you're rebuttal is that he is still weakened. I don't see how Vitiate being weaker than usual somehow stops him from being better than Sidious as of RotS.
First of all, what were you insinuating by this then?:
Secondly, in what fashion is a weakened form of Vitiate a superior combatant to ROTS Palpatine, who's beaten Yoda and blitzed 3 of the order's finest swordsman?

I'm saying that Vitiate, even when weakened, is stronger than Palpatine as of Revenge of the Sith when being fought in the Dark Temple and considering the way each battle went out. Do I think Vitiate> Sidious? No. I'm not even going to pretend such a thing is true. However, I'm more impressed with the power output from Vitiate than Sidious as of this time. I also think Yoda while maybe not as strong as Sidious probably could have defeated him. Star Wars characters do stupid things when the plot demands.
People shouldn't underestimate tanking Turbolaser firepower. Even ones from Troop Transport ships are 200 Gigatons per shot, which is High0end Island busting.

These things and more."
While I understand your points, the fact remains that Sidious, as of ROTS, is listed as the most powerful Sith Lord, ever. That is regardless of what's seen in the films, which isn't much, other than blitzing 3 Jedi. Let's face it, that duel with Mace left alot to be desired. Stunt doubles were needed.
It doesn't matter how powerful Sidious is. It's the feat I mainly care about. Vitiate showed more strength there, so his defeat is a greater feat. Using the HoT, they're more powerful than Scourge, fact, but if they had fought Scourge at the most just a month or two earlier, depending on the spacing of the chapter story-wise, they would have died. Painfully. Sidious can be as powerful as he wants to be, which is a lot he master Force Storm after all, but he has to show for it to matter.
No matter how powerful Vitiate was in general, his performance in the temple was terrible. HoT is a powerful and skilled character I accept but Vitiate's failure was bigger than HoT's victory there.
How is that even the same thing? Palpatine was extremely fast with the saber and he killed them fast. They couldn't keep up with him. Vitiate's failure is a complete different thing.
They needed someone to kill the Emperor or the galaxy would perish and they justified this unrealistic success of HoT by making Vitiate weaker than he normally is. Such a terrible storyline. Still quite impressive yet not enough to put her above Windu.
