Palpatine would destroy Snoke, unless the currently featless Snoke is some god-like entity. The Son & The Daughter vs The Father (Mortis trio)
If it had been Plagueis, it is not, Palpatine crushes Snoke. The Son and Daughter Luminara vs Qui-Gon
Luminara - Qui Gon was more of a philosophical Jedi rather than a combatant. Luminara and Barriss Offee vs Anakin and Ahsoka
ROTS Anakin, could take both Barriss, assuming she is alive at the time and is still full darkside vs Ahsoka, in Rebels
Rey Darth Bane vs General Grievious Side note: We really need a thread we can in-depth debate about duels and fights. I disagree with so much here but don't say it lest disturbing the flow.
Mace Windu- though Darth Cognus seems really cool had she been explored more. Jocasta Nu vs Betee and 0-0-0
