Gwen is without a doubt worse. She is a tart!!!! Rose was at least useful on occasion, and she sacrificed herself to save the world/the Doctor, whereas Gwen sacrificed Jack to save her boyfriend, who she had been whoring around on, and then sacrificed him AGAIN to kill the demon SHE released. Sorry her very name makes me want to rant *deep breath* There is not much love for Gwen in any of my fics (correction NONE) I think Jack should have fed her to the weevil in Ep 1. *grins at imagary*
