I don't know about you, but I'd say they both have strengths and weakness. I had a sith maruader that got cut down in battle many times because he was fool hardy and head strong. Whilest my Jedi Master killed Sion, the other guy and the final boss eaisly. My maruader got killed many times by the last boss. But with Master Force Barrier, Force Immunity, Strom Death Field, and a range of other master forms, I was eaisly able to defeat all bosses. If you have a high enough chrisima then you should be fine when using other powers. But my Jedi master had more HP than my Maurader, and hit harder and laster longer in the front lines. Maurder started as jedi guardian, master started as counsluar. It was funner playing as Sith, but made me hapier to play as Jedi.
