So i have played the Jedi Knight, Consular, and BH storylines. The Jedi Knight was the strongest of the 3 mentioned. However now im playing the Sith Warrior. I'm halfway through chapter 1. It feels really polished, and like a lot of caring went into this.

Right off the bat when you're on Korriban you go on a quest to get a really unique looking vibrosword that glows red. I friggen loved that thing. And it's little additons like the vibrosword that shows attention to details with that storyline. Another thing so far is vette. Vette feels very different from other companions in which the shock collar adds some uniqueness to how you interact with that character.

Also the story line itself feels very toned and serious. "Hey, there's a jedi that can predict and guess our every move...we need to find her". The sith warrior storyline has not engaged me like this since i played the knight.
