Well, RotS Sidious's skill with the blade is beyond any combatant here (for example he wins with Maul AND Savage in CW). He also dominates them with the Force (and they are strong enough to hurl spaceships with TK...)
Vader is a TK god as seen in TFU. He is also formidable with a saber.
On the other hand we have Malgus, who seems uber, but IMHO lacks feats to make him tiop-tier. The only thing memorable I get about him is when he’s throwing some heavy sh1t in the TOR trailer...but Vader and Sidious can replicate that with ease.
Lastly, Satele has a lot of hype, but she really lacks feats to back it up...so until more is revealed on her, she is not top-tier for me.
All in all team two is just better in every aspect.
Agreed, Sidious could solo this. Both Satele and Malgus were a bunch of flash. People can argue he was holding back, but in the middle of combat Malgus' lightning wasn't even enough to kill a normal human. Satele never showed any great offensive Force ability either. What you see of them is cool, but it doesn't amount to them being top tier combatants. I'd put Dooku and Maul up against them and expect them to end up dead.
