An Imperial Knight Vs a Jedi Master of the Republic. (please log in to view the image) (please log in to view the image)
Both are individuals at the top of their game (some would argue that Mace or Obi-Wan are better than Ki-Adi, but, that might be tipping the balance too far to the Republic, due to their skills so Ki-Adi is a more reasonable candidate.)
In terms of power, Mundi is a the level of knight. I don't think he even mastered his form. He was on the council for his wisdom. Only Yoda, Windu and Plo were wiser then him.
In terms of fighting ability: Mace Windu, Master Yoda, Anakin Skywalker, Obi-Wan Kenobi, Plo Koon, Kit Fisto, Shaak Ti, Agen Kolar and Saesee Tinn were all greater then him. Stass Allie and Aayla Secura were the only masters on the council that were weaker then him.
As explained in the AOTC novel, Mace thought the Jedi could win because "The Geonosian's arn't warrior's. One Jedi has to be worth a hundred Geonosians." He didn't know that they would have to confront thousands of battledroids. And if one standard jedi = 100 Geonosians that means Jedi like Kit, Luminara, Ki-Adi, Plo Koon hell even Obi-Wan must be worth several hundred, and Mace himself maybe over a thousand.
Antares Draco may be the top of his game, but we haven't seen anything with him in it...yet. Perhaps Legacy#2.
Aayla Secura was not on the Council, whoever said that.
And Ki-Adi-Mundi seemed to be the third most important person on the Council. He did take on General Grievous (CW) alone at the end of that fight, though considerably fatigued from the earlier parts of the fight and the war with the droids on Hypori beforehand. He didn't win, but he stood his ground.
No, I didn't say that at all. Re read what I said:
I said, that both Mace and Obi-Wan are better than Ki-Adi, so they might be too much of a challenge for Antares. Ki-Adi on the other hand, not being as powerful or skilled as them, might be a more evenly balanced opponent.
He might have been struggling, but he still stoood his ground agaisnt Grievous, rather than the Jedi who had his face whipped into the floor, or the ones who were flung into the roof...
Ki-Adi didn't miss Grievous, precicely, it was just that Grievous had fast enough reactions to move out of the path of the shockwave once it was channeled. Also, I believe Shaak Ti (or one of her posse) also tried Force blasts on Grievous, which he was also able to avoid.
I just watched the fight scene. Ki-Adi-Mundi was the only person to attempt to forcepush Grievous, and he missed. Shaak Ti telekenetically threw some rubble at him, but he dealt with it with his saber. And Vious, you claim to be a swords expert right? If you were, you would know that Shaak Ti fended off Grievous far better then Mundi did.
