You'll notice that your ABC logic is poorly applied here.
Makashi; heavily precise dueling form designed solely for one on one combat, ideal for picking apart one's defence while conserving as much energy as possible, using the minimum amount of movement required.
Soresu; a purely defensive form designed to tire opponents out and wait for them to make mistakes, which has a root in blaster bolt deflection, opposed to dueling.
Makes sense that Dooku does well against Kenobi when he's already a little bit more skilled than him, his dueling form covers every potential weak area Soresu seeks to exploit, and from there Soresu simply isn't aggressive enough to (it lacks aggressive qualities altogether really) push a Makashi practitioner. Kenobi's Ataru? Dooku's remarked that he knows every facet of the form, every weakness, which is why he suspects he would have defeated Qui-Gon without much issue should they have ever fought.
Kenobi's style of combat is much better suited to facing Juyo than Makashi; it's not advantageous, but it's better than any other for fending off the erratic, speed and strength based assaults designed to flatten someone's defence ASAP.
And more on that point; Maul's brand of Juyo is better suited against Dooku's Makashi than Kenobi's Soresu, due to the maximum efforts placed on aggression, striking strength, speed, unpredictability and kinetic movement. It keeps Dooku on his toes far more, wears him out more quickly, and is a much more difficult assault to launch a counter-attack against.
Setting aside style advantages; Maul and Kenobi are both praised as being among the best duelists in all of recorded history with the feats to back it up, as you know. Windu and Dooku are better, but by a slim margin.
And more to the actual point I was making: no, Dooku's not taking a "large" majority on account of a power Maul can circumvent better than most of Dooku's competition.
