Let's look at the movies though. Mace beat Sidious who beat Yoda. This is reinforced in the EU because Mace is reveared for his lightsaber skills by just about all the Jedi.
Even when two equals meet in battle one will win some way or the other.
Besides saying Mace beat Sidious will spark a huge debate about whether Mace won or Sidious was faking.
As for the EU Mace is reveared for his saber skills, but not just because of how good he is but because he invented his own style of combat Vapaad.
I know, been there before, but when you consider the toll the battle with Mace took on Sidious, physically, if Anakin hadn't showed up, Sidious would've been toast. Wasn't Vapaad, if I remember correctly, taught to him by the older Jedi (I forgot) who was the first to jump ship in the Clone Wars series to Dooku's cause. He was the same race as those guys on Jabba's skiff.
Sora Bulq but he didn´t invent Vaapad, Mace did.
If Anakin hadn´t showed up then Sidious hadn´t reveled himself as a Sith lord to Anakin in the first place. What I am trying to say is Anakin have to be there not only because Sidious made sure he would come (PALPATINE: You do know, don't you, if the Jedi destroy me, any chance of saving her will be lost.) but because it is his destiny to be there. Nothing happens by accident in Star Wars.
Granted, and I'm not saying he wasn't planning to have Anakin there. But if Anakin hadn't arrived, judging by just how badly Palpatine'd become physically (which I'm guessing was NOT part of his plan), Mace would've destroyed him.
I don´t think he planned to be disarmed either but Palpatine has always all the aces up his sleeve. He would win no matter what. For example, we don´t know if he had his second saber concealed inside his other sleeve. That if we don´t count Anakin would be there for sure.
And Palpatine wasn´t injured or wounded, He got his scars as a result of a Dark Side reaction.
That's another debate in itself.
Lucas said Palpatine wasn´t tired or weakened at all in the Making of Episode 3 book so it can´t be an injury. And Pablo Hidalgo said it was a Dark Side reaction.
