Sabers only
Ventress is superior to Kas'im, on par with Bulq and Kolar, and below Vader.
Fisto is below Bulq and Kolar slightly, below Vader clearly, and above Kas'im.
Sion is below anybody on team 2, but his indestructibility is a huge wildcard allowing to cheapshot somebody defeating him.
Tholme is around Kas'im.
Team 2 here, imho. Vader > Kolar=Ventress=Bulq > Fisto > Sion = Tholme = Kas'im.
Force only
Ventress is above anybody, sans Vader - and Vader is inhumanly superior.
Fisto is below anybody sans Kas'im, and leagues below Vader.
Sion is a wildcard entirely.
Tholme is above Kolar and Kas'im, below two others, inhumanly below Vader.
Team 2 wins because of Vader's presence.
All out
Obvious. Team 2.
