I've only completed 2 stories so far (Knight and Consular), and of the two, I very much prefer the Knight's story. In fact, I enjoyed it a great deal. I confronted the big bad, saved the day, got the girl, all while swinging a lightsaber, and that's exactly what I signed up to a story driven Star Wars game for.
My only problem with the story was that at around the end of chapter 2, I was forced to
which I didn't want to. That disappointed me a bit.
