@Ching: Probably not. Between his Force defenses and his lightsaber, he's no more susceptible to lightning than any of his contemporaries.
Sure, his cybernetics might be vulnerable, but so is flesh. If they're powerful enough to destroy his cybernetics, chances are they don't need lightning to win anyway.
Force: Extremely close, but team 1. For me Force goes 1. Vader 2. Arcann 3. Dooku 4. Malgus 5. Outlander.
Sabers: Extremely close, really can't decide. I'm leaning team 2, barely, though.
All-out: Tbh no matter who he's paired up against, I see Maul going down first. That's enough to give team 1 the win. It's extremely close, and there's so many ways it can go down that I see it only really being ~55% in favor of team 1.
Excellent fight and thread 👆
