I'm kind of unsure as to how Soa vs Sel-Makor would go. They're both immensely hyped but as good as their feats are, they just don't quite live up to that level of hype. I'd easily side with Soa based on showings, to be honest, but as Sel-Makor at full power without resistance from Vitiate is the version being used here, I'm really not certain as to how the fight will play out now.
Traya vs C'baoth is interesting. TP won't be a winning factor here, since they've both demonstrated pretty insane showings in the area. C'baoth brings stronger (demonstrated) Lightning, while Traya brings greater Telekinesis, greater durability/agility and the chance of using Drain. Her edges probably aren't quite as extensive (the degree to which C'baoth's advantage matters depends on how well Traya can defend against C'baoth's Lightning), but she definitely has more. I'd give her the edge.
Sidious could face Talzin in another near-stalemate, but for the sake of it I think it'll be more appropriate for Gethzerion to contest with Talzin for Nightsister supremacy while Sidious faces his rip-off TOR counterpart. I've always favored Gethzerion over Talzin, but now I'm actually not too sure because of Talzin's performance against Sidious. Sidious takes Vitiate in an excellent contest.
So I favor one from team 1, one from team 2, and the other two match-ups I'm uncertain of. It'll be interesting to see what others can bring to the table here, although it's kind of been disappointing so far.
