I have a 50 Sniper and a few 30s on the Sith side.
I really dug 'being a bad, bad person' in the storyline.

Rolled a Pub Trooper, and am really enjoying how it plays and the storyline (better play, IMHO than BH). Finding it really hard to make Light side choices, though, lol.
If you get tired of one side, try the other and vice versa. Do all of the quests. There is a lot to explore on both sides.
