The trick against Yoda is to win the edge battle. =P
Seriously, Sith control I would say is about 50/50 toss up between them and the jedi, though your odds go up drastically if you have Council of the Siths / Recon Mission out. If you don't, Fall of the Jedi at least lets you filter to your more powerful cards, which you can play or edge away. Also, if you have Vader in play it drastically helps. Heart of the Empire set, while most people don't like the objective, can really help with Force Stasis and the Coruscant Defense Fleet can beat up Jedi pretty well if you win the edge even if they have a Guardian out. Icetrompers aren't bad at doing 1-2 damage. Luke and Old Ben are trickier, so you just have to go in with multiple defenders and all the tricks in the book.
If Counter-Stroke and Lightsaber Deflection are problems for you, you can run Lord Vader's Command which can increase their costs and you get Imperial Suppression to mess them up. I personally wouldn't worry about these as much because you can usually tell when they are coming and play around them (don't attack and control the force, or if you're defending just try to win the edge battle to minimize damage). If you're worried about enhancements, splash for Take Them Prisoner so you can run Tear this Ship Apart, which also has the great card Detained which can get around Old Ben. Or if you wanted to go that route with capturing, Boba Fett can also bypass Old Ben or capture guardians.
Of course, the best objective set against the Jedi is Cruel Interrogations, as the multiple non-edge dependent tactic icons on the droids really help out, not to mention the fact you get Interrogation, which is a great catch-all answer that can really mess with the opponent's tempo.
Hope that can help a little, or at least put things in a little better of a perspective.
