Sabers only - PT definitely.
Legends Quinlan is better than Ben or Tahiri, and should honestly be superior to Vestara too, but that can be debated.
Nearly the same goes for Tholme, although I'm willing to give Khai the clear edge here.
Aayla bests Ben, and probably Tahiri too.
Force only - I honestly dunno. Ben is definitely better than Aayla, and given a good timing, he can overpower either Quinlan or Tholme. I completely don't know about Vestara, especially against Tholme, whose skills are pretty tricky, and Tahiri should be below Vos or Tholme, but above Aayla. Depends on the matchups, I guess, and it's still debatable.
All out - the same as sabers only. None of the combatants here are Force wielders of such a level that Force fight would dictate anything
