The strongest character Jaina Solo and Jaden Korr would beat for majority?

FotJ vesions of both. Standard gear, in character but determined to win, very good level of cooperation, neutral battleground.

What is the strongest character they can beat for majority?

I would say someone along the lines of SOD maul or ROTS Kenobi, perhaps higher . However, I’m still unsure on where Jaina stands due to her lack of feats, which doesn’t support her admittedly very impressive saber accolades while Korr can provide support via his decent TK and scaling.

possibly someone on a nivel similar to rots kenobi or dooku

Rots sidious
