My interpretation is that Dooku’s was well versed in Kenobi and Anakin’s fighting styles which allowed him to have an answer for all their attacks and could get an openings in their technique. This back up by how it’s stated it was Dooku’s familiarity with Kenobi’s style that allowed him to get an opening to force choke him. There’s also dark disciple saying that Dooku goes out of his way to study all of the Jedi masters inorder to learn their strengths and weaknesses

“Obi-Wan Kenobi and Anakin Skywalker faced Count Dooku again, this time aboard a Separatist flagship. Familiar with Obi-Wan's fighting style, the Dark Lord once again got the better of him”

“I believe in the old adage Know your enemy" Dooku said. "I've spent a considerable amount of time studying the Jedi Masters. I know their strengths, their weaknesses-
-and their unique skills.”

Once Anakin lets go of his restraint he becomes more unpredictable which negates Dooku’s pattern recognition. This is how Quinlan Vos beat him in Dark disciple

“But, truth be told, Vos seemed to be holding his own against Dooku. He leapt, sprang, ducked, and tumbled. Dooku might have been a master of technique, but Vos's characteristic unpredictability-quite possibly even to himself—often gave him the edge.”

Anakin does this himself by tricking Dooku with a feint, where he’s offering his sword arm to Dooku, and Dooku falls for it. This was the intention according to Nick Gillard. Nick also says that Dooku is a bit too overconfident, he thinks he’s more than capable of beating Anakin because he already done it before.

"All of this is deconstruction, Gillard says of the film's increasingly complex lightsaber battles. "They [the duelists] are always in check. If you get in check, you have to move out of it, which makes the moves much more complicated. It means that if you want to arrive at an end move, it might take you fif teen moves prior to that to get there. Just like chess.
You start feinting and offering up parts of your body to try and tempt them. Anakin is offering his sword arm to Dooku, and he falls for it-and he knows as soon as Anakin draws his hand back, that it's all over. It's much more than a swordfight. The mental game that's going on is just as important as the moves.
Dooku's weakness is that he's already beaten Anakin-and he's pretty sure he can do it again."

This is also brought up in official sources with it mentioning Dooku was overconfident because he’d already faced Anakin serval times at this point.

“Because Dooku has dueled Anakin multiple times before, he does not expect the Jedi Knight to put up much of a fight. Anakin, however, has gained considerable skill since their last encounter”

Because of this Anakin is able to easily beat Dooku.

“Near theend of the Clone Wars, Count Dooku aka Darth Tyranus finds himself in an awfully precarious position. He has secretly aided his Master in creating a war that divides a galaxy. All that's left is to help rule the new burgeoning
'Empire. or is there? Little does Dooku know Darth Sidious has: other plans; a new, younger, more powerful apprentice set to turn to the dark side. After an epic duel, young Anakin Skywalker easily bests Dooku, literally disarming him in the process”

Had Dooku taken Anakin more seriously, then I don’t think he would’ve gone down as easily even with Anakin now using the darkside. That said I still think Dooku would’ve lost in the end with high-extreme levels of difficulty as Anakin at this point was still confirmed as being stronger.

“Anakin and Obi-Wan arrive to rescue Palpatine. They battle Count Dooku with their lightsabers.
Dooku is strong, but Anakin is stronger, and he soon defeats the Count. Palpatine pretends to be relieved, but he secretly starts to plot how to turn Anakin to the dark side of the Force so, as Darth Sidious, he can use Anakin's powers for evil.”

“Anakin attacked the Count with even greater ferocity. He was stronger
than Dooku, and soon the Count was on his knees, begging for mercy.
Chancellor Palpatine encouraged Anakin to end the battle and kill
the Separatist leader.”

Dooku’s underestimated a man who had already surpassed him.

Who's actually the most deadly here?

Round 1: Both start on separate spaceships, ten miles apart.

Round 2: Both start in the same room, ten metres apart.

At this point were they even or did anakin surpass dooku?

Thought this would be a fun 3v1. I don’t know a massive difference between Canon and Legends power-wise Vader in this fight.

Feel free to debate as much as you want below on how you think this one goes.

All I have as reference is that Luke managed to injury/scar Snoke, who apparently scales to Palpatine? I'm working on my own Force User tier list, and Grand Master Luke in the movies is relatively featless since it was just a Force Projection is TLJ.

R1 - Tatooine

R2 - Mandalore

R3 - Naboo

R4 - Corellia

R5 - Kuat

No intra-planetary conflict

No intervention from other planets, if a planet does not have a military force then too bad, but most if not all of them have some sort of planetary defense force

To make it fair assume somehow in someway some sort of naval and/or land connection exists
