I'm going to go Lok and Trill. While neither is quite a match for Xesh, I do believe they hold an edge over Lanoree, as both are some of the more impressive force warriors of the time.
Lanoree is no slouch, beating her brother like she did (and her brother in turn able to score a hit on a Noghri Je'daii master), but even so I don't think she's as direct-combat good as the others.
