The Chosen One
Bane has no dueling feats that remotely compare to Surik's handling of Imperial Guardsmen and complete slaughter of the Sith Triumvirate on Malachor V.
Bane was getting thrashed in a duel by Raskta Lsu despite having literal plot armor and two amps to her own comparatively minor one.
Surik also has superior Battle Precog and Echani Precog feats than Bane can compare to, Lsu proved this case in her own right. Surik analysed and reacted against, almost immediately TK killing a merc, all in the space of half a second, goodluck blitzing that.
Bane has nothing on his belt without nexus amplification to suggest he is superior to Surik.
Also I'd love to see how you think Zannah > Traya in any department Neph.
Zannah uses mental assaults and the horror variant pretty exclusively off nexus, taking down Jedi such as Sarro Xaj. Traya has manipluated the minds and memories of numerous Jedi, including Jedi Masters without them even knowing about it.
Zannah has used Force Cloak techniques to strong degrees, enough to get a stealth kill on Lsu in mid-combat. Traya uses such techniques constantly with apparent ease to their highest degrees, hiding in plain sight from Jedi Masters and even travelling companions.
Zannah has with the aid of Lake Nath, an immense Dark Side nexus, summoned tendrils of pure Dark Side energy. Traya has drained Jedi Masters and Sith alike with ease and has shown Dark Healing abilities of the highest degree., all without a nexus.
Zannah has telekinetically assaulted Jedi and Darth Bane, Darth Traya effortlessly ragdolled High Council members with ease and has shown complete mastery of telekinesis with telekinetic lightsaber combat.
I could go on.
