Depends of the setting. Assuming open area without many objects, Dooku takes all. If it will be open area with many objects, then Vader takes the Force and possibly all-out, if he can spam Dooku with TK.
Area without objects, would force Vader to engage Dooku in lightsaber duel. As we could see in the Rebels, Vader is moderate skillful fencer at best. He couldn't even beat Ahoska, while being on DS nexus. He did better then Maul, as he could somehow overhelm her, but he was unable to beat her. He also couldn't pass rusty's Obi-Wan defense. Canon Vader was also unable to break a Force guard of Ben's and Ahoska's level. He wont do that with Dooku's. So all-out in that scenario will be very similar to sabers only. And Dooku will takes it.
Force fight in a place without objects will let Count Dooku to do a first move. Lightning, I guess. And without a saber to defend, and TK not much superior to Dooku's, Vader will finally fall.
Area with a lot of objects:
Dooku takes a sabers, like before.
All-out and Force would go to Vader this time. He can spam Dooku with his superior TK - he should have small advantage at the beggining, and much bigger at the end, as Dooku will lost his stamina and Force reserves much faster. Vader should be able to tank Dooku's FL for a moment, so even if Dooku will hit him with that, Vader's response should be TK.
Small area? No idea, but that's the only place, where Vader might takes sabers and all-out, while Dooku might takes Force only fight.
Yeah, perhaps he is as powerful as statements says him to be. But that doesn't change the fact, that he's a terribly ineffective during combats with other Force users.
Within a Temple on Malachor, being amped by DS nexus, all three Inquisitors could held their own against Ahsoka (unlike in a duel on neutral ground, when she bested them 1 vs 2). Even Maul did a better worok against them then Ahsoka did, and at the end, he was able to stalemate her. Vader - who somehow must be amped too - was unable to easily overhelm her. Perhaps should would be even able to beat him on neutral ground. Yeah, the same girl who couldn't stomp the Inquisitors. And then, Vader confirms his lack of talent, by being unable to beat old Ben in a fair fight.
By canon showings, Dooku takes this. But Vader still can take "more powerful" title. That wont change the outcome at all. People like Anakin, Mace, Dooku (perhaps TCW Maul) - who are superior duelist by solid margin, and inferior Force users by small margin can all take him.

Vader decisively.He's already struggling with Anakin's strength in Crisis on Naboo and Vader has been confirmed to be far more powerful, so he stands no chance of winning sabers despite his skill.
In the Force his feats are head and shoulders above Dooku's so he should take that comfortably as well.
😂
That's one of the very few Quanchi's points, that might be rightful. As I remember, some of you guys, tried to prove, that Ahsoka was superior to Maul in Rebels, due to the fact that there was stalemate between them, and he was amped by DS nexus.
Sadly, Vader was amped as well, and barely able to overhelm her. Let alone defeat her.
Until Ahoska/Ben/OM Maul will be proven to be above Mace or Dooku, Vader should be consider as inferior combatant to Mace, Dooku, Anakin, TCW Maul. Even despite the fact, that Vader is more powerful then any of them.
None one the enemies Vader fought have any saving graces, the last bastion of hope was through Maul admitting inferiority, but we've all seen what's happened to that sack of apples. I agree with the assessment that Dooku, Mace & Anakin types all simply better combatants until there is strict evidence otherwise.
