who's もっと見る powerful, jafar または rumplestiltskin?

what i would really 愛 to see is jafar and rumple meeting and going head to head with each other. one thing i'm curious about is who's もっと見る powerful? the dark one または the one who has his own powerful magic plus possesses the magic from his girlfriend/teacher who was a very powerful sorceress before she became his snake staff
