Saba Sebatyne vs. Asajj Ventress

Round 1: OCW Ventress as of her duel with Anakin

Round 2: Peak Ventress

Battle takes place on neutral ground

Going by feats Ventress. Though personally i think Saba would win after a tough fight.

-

OCW Ventress loses, but prime Ventress could possibly pull it off.

Saba solidly. She is badass enough to beat Abeloth in 1x1.
