I would have to agree with this post and this is coming from a Republic player. The main reason why I hated the Sith Empire were because of the psychopath emperor and constant backstabbing. For some reason, I don't see those problems in Malgus Empire.
Think about it, remove all the down syndrome sith (basically 98% of the sith population)who would kill anyone in sight, ensure you're working together for the benefit of the empire and you almost have an unstopable force. Only reason why Sith keeps and will keep losing war is because of their arrogance and incompetence... (that and because George Lucas likes good guys)
