Overall, Dooku was far more equipped to become a Sith Master than Maul was. Had he managed to overthrow Palpatine, Dooku would have been able to use his position, combat abilities, and dark side Force powers to take his place on the throne Palpatine had carved.
Anakin Skywalker was one of the strongest Jedi in the films and Darth Vader was one of the best Sith. It only makes sense that they both could have decimated Darth Maul if they faced him. At the peak of Anakin's power, he was able to take on Count Dooku and win, and went toe-to-toe with Obi-Wan on Mustafar.
That notwithstanding, Master Windu was also one of the best. If the two spared as Jedi, Dooku would probably win the match because he was the better all-around duelist.
Although he was not quite as powerful as Anakin Skywalker at his peak, Dooku was still one of the most powerful Force-users in the history of the galaxy; arrogantly claiming himself to have been more powerful than any single Jedi of his time. Dooku's Force sensitivity was equal to Mace Windu's.
We were ROBBED of the BEST Lightsaber fight in Star Wars
Can Maul beat Dooku?
Had they fought one another at their full potential, Maul's exceptional lightsaber skills would have been difficult for Dooku, but Dooku's knowledge of the dark side of the Force would likely have prevailed.
Sidious one-shotted 3 of the best duelists of the Jedi, he is certainly more impressive than Dooku as a duelist, Dooku would have a close fight with Maul and struggled with Savage and Ventress at the same time, Sidious on the other hand beat Savage and Maul at the same time with extreme ease, those two were nearly ...
7 Why Rey Couldn't Win: Dooku's Skills Far Outshine Rey's
Rey was able to triumph over a lot of foes through sheer pluckiness and a good mixture of luck and sheer Force power. That won't help her against Dooku.
The duel. Darth Vader defeats Darth Maul. The two Sith Lords engaged in a lightsaber duel, going through the volcano and onto a bridge situated over a river of lava, which collapsed, though they both survived and continued their battle.
It's already been shown in the source material… more than once… that Darth Maul is not on Darth Sidious's level. Every time he dueled Sidious as his apprentice (in Legends) he got easily defeated. In the show Star Wars: The Clone Wars, Palpatine takes on Darth Maul and Savage Opress simultaneously.
Sidious revealed to Maul that he did not intend to kill his former apprentice, as he still had use for Maul; it was Sidious' hope that Maul would lead the Sith to Mother Talzin, Maul's mother and the leader of the Nightsisters, so she could be eliminated as a potential threat to the eventual Sith rule of the galaxy.
He fell under the influence of Supreme Chancellor Palpatine of Naboo, and left the Jedi Order. After learning that Palpatine was secretly the Sith Lord Darth Sidious, Dooku turned to the dark side and became a Dark Lord of the Sith himself, replacing Darth Maul as Sidious's second apprentice.
Dooku despises Maul for being a threat to him, and for killing his beloved padawan Qui-Gon, and Maul hated Dooku for being his replacement. They also didn't regard each other as a true Sith: Dooku saw Maul as nothing more than a trained animal and Maul saw Dooku as a Sith pretender.
Dooku's vision for the Empire was superior to Palpatine's, as he aimed to transform the Jedi Order into an unstoppable Sith Army. His talents as a Force wielder, though outclassed by Palpatine and Yoda were also top tier, as nearly all Jedi were unable to withstand him.
Kenobi would and has lost to Count Dooku on multiple occasions. This was primarily demonstrated through the prequel movies, where he was overwhelmed in Attack Of Clones and defeated in mere seconds on the Separatist flagship during Revenge Of The Sith.
The count bested both Jedi in their duel, using the power of the dark side and taking advantage of young Skywalker's impetuous nature. But before he could land a killing blow, Master Yoda entered the fray. Not even Dooku's Sith-enhanced powers were enough for him to defeat Yoda.
Obi-Wan Kenobi was considered to be one of the greatest Jedi swordsmen of all time. A practitioner of Form III: Soresu, Kenobi was considered the greatest master of the form ever, just as Count Dooku was considered the greatest Makashi practitioner ever.
Darth Maul was Darth Sidious' apprentice and the final antagonist of 1999's The Phantom Menace. Given that he killed Qui-Gonn and nearly overpowered Obi-Wan on Naboo, he is an exceptionally gifted lightsaber duelist. After Maul returned in The Clone Wars, he became a dangerous wildcard.
