I voted for Ohno. Barret takes a little to long to set up the Bull Hammer whereas Ohno just hits it out of nowhere. Also, Ohno's elbow sounds like it hurts.
I personally like Barrett's elbow more. The setup makes it seem like more of a finisher to me. If I saw Ohno's elbow for the first time, I wouldn't be sure if it was a finisher or a regular move.
