ThanosiNo.
Also my friend... that is only ONE name opponent for the 3 I listed. Which is my point... narration and practice performances only go so far.
What the thread starter is trying to get is an idea of who in the mythos possesses top-tier technical skill with the lightsaber. The term as we use it connotes one's mastery of form, style or technique, classical, obscure or improvisational. It's a topic of interest to the thread starter in part because it isn't usually dictated by the trajectories of traditional duels in canon; those are generally determined in at least equal measure by a number of other factors, including psychological elements and variances in combatants' respective abilities in the Force.
Now:
Kas'im: Path of Destruction makes it perfectly clear that Kas'im's expertise in the methodology of lightsaber combat is unmatched in his time and nearly so in any other. His performance against Bane sets this in stone; despite Bane's tremendous advantage in Force-talent - not to mention age, strength, size, and familiarity with the environment - he has no defense for the alien style Kas'im utilizes in the end-stages of the duel. As this case relates to this particular thread, the fact that Bane was completely unfamiliar with the dual-blade style is not a mitigating factor in the value of the swordmaster's victory, it is proof of his complete dominance over Bane in the discipline whose cross-saga elites this thread is trying to identify.
Ulic Qel-Droma: Over a decade after being violently cut off from the Force, with his only practice in recent days being the relatively brief training of a Jedi child, he held his own against a bloodlusted Sylvar in combat.
That might not sound particularly impressive, but keep in mind a few things:
[list]
[*]Ulic had spent the past ten years wandering the galaxy, spirit broken. Put on trial in front of the Senate for crimes against humanity - a charge that wouldn't be invoked again for another four thousand years - immediately before the assassination of the Chancellor by his Sith Master, one would imagine his standing with the galactic populace (a pilot who identifies him ends up shooting him in the back) indicated that he hadn't spent many of those years in anything resembling comfortable conditions. His health and athleticism had presumably suffered as a result, and he didn't have a lightsaber to practice with; the one he used against Sylvar was built one on Rhen Var by hand without the aid of the Force.
[*]He had no connection to the Force. This means no heightened senses, enhanced reflexes, or superhuman strength, speed, and stamina. Nothing that makes a Jedi extraordinary.
[*]His opponent had all those things, in addition to her species' inherently superior physique and the further enhancements of strength and speed provided by the battle rage she'd immersed herself in.

I'll point out that the best of non-Force-sensitive humans tend to compare rather poorly to even the most reserved of Jedi in close combat. Jango Fett, trained Mandalorian, genetically prime and the most dangerous bounty hunter in the galaxy, took on Obi-Wan with pistols, a rocket launcher, and starship cannons controlled by a [very capable] third-party, and managed at best to run away. Another Mandalorian attacked Kenobi with a lightsaber during the Clone Wars. Despite putting up an impressive show, he was disarmed and humiliated. Entire sections of The Cestus Deception are dedicated to the awe Kit Fisto inspires in ARC troopers, the most gifted and effective soldiers in the clone army.
As of Redemption, Qel-Droma was no longer a physical specimen of any note. He had no power in the Force. The only thing that could possible have enabled him to withstand the assault of a murderous Jedi, someone quick enough to deflect blaster bolts and strong enough to beat down Massassi, is an enormous command of the lightsaber. His skill is completely unquestionable.
Someone with the relevant [non-Darsha Assant] sources can tell you about Bondara. Again, given the issue we're dealing with in this thread narration is usually going to be at least as important as action. Don't forget that.
