Ok, so I gave it some thought, and here is my analysis:
Dooku vs. DoE Bane
Sabers:
Dooku is considered to be one of the best duelists in Jedi History. He’s a master of ultimate dueling form-Makashi. He was able to contend with Yoda, and is more or less equal to Windu, he effortlessly saber-handled Grievous and Ventress (CW mini). Dooku is faster than Kenobi, who is himself extremely fast. Again, Dooku was able to compete with Yoda, who himself is an absolute top tier speed-wise.
DoE Bane is a Djem So practitioner with of one of the fastest learning rates in history. He was able to match Kas’im only a after relatively brief training. Bested Rastka Lsu (though when enhanced by the Orbalisks), was beating Zannah, who is said (I believe) to be extremely proficient with Soresu. His DoE rain feat is pretty uber. He is physically powerful and his Djem So might be problematic for Dooku to handle, but not to a degree of Anakin’s Djem So. (Anakin can dish out more raw power). DoE Bane has his uber rain feat (though some pointed out that rain drops travels slower than blaster bolts). Nevertheless, it was a middle of a pouring rain so his speed must be extreme.
Force:
Dooku seems to have better TK feats like collapsing caves, collapsing bridges, TKing Jedi of Kenobi’s caliber effortlessly, his FL was powerful enough to kill Kiffari warriors, to easily subdue Ventress, Anakin, Savage and while drugged and blinded he used it to beat Ventress and and two other nigthsisters.
TBH I’m not well-versed in DoE Bane force powers. I assume his FL is more or less the same as his RoT incarnation and thus seems to be more powerful than Dooku’s. His TK is impressive, but I cannot remember any of Bane’s TK feats from DoE. Bane possesses some unique skills like death field, but I’m not sure if it will come into play in this setting.
All-out: I’m inclined to give it to Dooku. Overall he is a superior duelist, his force feats are better, though DoE Bane most probably has a more powerful FL. Speed-wise DoE Bane might be faster, but not to a degree that will make a difference. Dooku 7/10
Anakin vs. Zannah
Sabers:
Anakin is the finest practitioner of Djem So Dooku had ever seen. He probably mastered this form. He was able to push Kenobi back, even though Kenobi knew his moves intimately. When pissed, his ever growing stamina and power enhance his saber skills to a degree that he makes short work of Dooku. He is extremely fast and agile.
Zannah was trained in Soresu and probably mastered this form. Soresu relies on dragging out the duel, tiring out your opponents and exploiting their weaknesses. She was able to contend with DoE Bane, but as far as I remember, she was on a losing end in that saber battle.
When facing Anakin Zannah is at disadvantage because Anakin’s unparalleled force reserves will ensure that he will only grow in power throughout the duel.
Force: Anakin seems to possess very good force defenses, he was able to shrug off most of Dooku’s force attacks at numerous occasions. Still, he was also force-handled by Ventress and Savage at some point. His TK is good, but he rarely uses it in mid-combat.
Zannah was a force prodigy from a very young age. As a child she broke the necks of two Jedi and atomized her friend’s hand. Later on she became skilled in Sith Sorcery, but I’m not sure to what degree it will be effective against Anakin. It seems that Zannah has more complete mastery over her force capabilities and a more versatile range of techniques that she can use. Raw power goes to Anakin, though.
All-out: Here I’m inclined to give the edge to Anakin. He has extreme force power reserves, is most probably a better duelists, his force powers are also quite good, and even though Zannah seems to possess greater mastery and refinement in her force abilities, it will be not enough to put Anakin down.
Maul vs. Satele
I’ll reiterate my points about Maul.
Sabers:
Maul’s praised as an extremely skilled duelist: "One of the deadliest Sith Apprentices in history", master of Juyo, thus a master of multiple lightsaber forms, has great speed, knowledge of Teras'Kasi martial arts IIRC. Maul defeated Bondara (who was said to be unmatched in technical skill with a saber... Kas'im I'm looking at you), defeated Qui Gon, effortlessly defeated Savage, matched Kenobi in sabers). He is also noted for his impressive speed and agility.
Satele: ... Hmm here I admit I have almost no knowledge on her notable saber feats. In Hope trailer she was pwning some random Sith and holding her own against Malgus … Unless someone can provide good saber feats for Satele, I think Maul is a clear victor in sabers..
Force:
Maul’s TK is impressive: pulling down a ship from a rock, TK'ing Kenobi numerous times.
Satele seems to be portrayed as a powerhouse, but from the top of my head I cannot really remember her force feats from the book. Yet, from what I’ve seen in the trailer, she has a very powerful force push, enough power to topple a large tree and a unique ability of energy absorption. Importantly, she seem to rely heavily on her force powers in combat, and this is a smart move against Maul who in close combat is an absolute beast.
All-out: In this case I’m genuinely undecided, mainly because I don't know the extend of Satele’s saber and force feats. She appears to be portrayed as a force titian, but as a duelist? I dunno.
team 1 vs. team 2
As of now I'm inclined to give an edge to team 1. They take it 7/10.
Unless DoE Bane and particularly Satele are more powerful than I give them credit for, this is my opinion on the matter.
