Tough one, they're both the same in too many ways.
Arguably Ulic will take this as Vastor isn't amped, but their feats are close. Ulic will probably take force as by a slim margin, but Vastor should take durability.

Ulic actually has bonafide Force training and is a master swordsman who can no-sell artillery style blaster fire with what looks like a Force Bubble. Vastor can beat him in maybe wrestling, but that's it.
Didn't he dodge those blaster bolts? Iirc he was running from Mandalore in their fight when they first started.
