So not true...I cant stand Jedi's...or Sith for that matter. Hell, I dont even like Star Wars, but I do enjoy this game because of its design.
that said, the PVP battles seem to lean in the favor of the most 50s.
I wont say which side is better because it seems both have their shining moments. Personally I have experienced the republic winning most...in fact I am on a 10 warzone losing streak to the republic. (I should point out they had all 50s, and a bunch of healing Troopers).
