DoE Bane vs. 30 Vong Slayers

*Sabers only

Bane is in Full Sithari mode.

Slayers have their modified Amphistafs, their coufee knives, and 20 vials of Blourash jelly

Who wins?

Bane fulfills his prophecy and dies, destroying the sith.

Bane saber soloed several Tuk'ata. A single Tuk'ata gave Soara Anata - the best lightsaber instructor of the time and thus canonically better than Yoda(tho still inferior to Scourge) - a lot of trouble.
So Bane = Scourge > Soara Antena > Yoda > couple of bitchass Vong.

Exactly Bane beat beasts that can't even wield lightsabers, this makes him a perfect fight for a warrior race like Vong.
