In the SW vs JK for me they are even I play the 2 of them to 50.
For the Emperor, the Jk didn't kill the Emperor it was just a body he use, and the SW kill another body the emperor use that why for me they are even, and in the SW quest u have to kill a Emperor body controled by Sel Makor, so I don't really know =).
