The Sith Warrior and Sith Inquisitor are also very excellent all of the way through (I rate Sith Warrior as #3 personally).
The Trooper is great in Act 1, then fizzles out (bonus points for having exciting Act finales though).
The Consular is the most underrated storyline in the game, but I do like it a lot.
The Bounty Hunter had a decent Act 1 and for me quickly fell flat the rest of the way. I could not get into it, but I did enjoy grappling enemies and giving them rocket-powered uppercuts.
The Smuggler has been the worst storyline for me because I still haven't finished it. Each time I try I log out within a few missions. But the dialogue choices are pretty entertaining.
