I can't really see Jinn outdueling Shado. He doesn't have much to surprise him with (Talon's Ataru didn't bowl Shado over) and Jinn will definitely tire more quickly. The saberstaff striking from multiple angles at twice the frequency of a regular blade will only make Jinn work harder as he did with Maul.
Sazen isn't all that different from Kenobi either and is certainly the more seasoned fighter, having spent years and years killing Sith ambushes while outnumbered, participating in numerous large-scale battles with lots of Sith, and stalemating one of Krayt's head lieutenants.
