User blog:SoMaShadow/Haruhi Suzumiya opponent

I would like to potentially have Haruhi Suzumiya from the Melancholy of Haruhi Suzumiya as a combatant in a fight. The two possible opponents I have planned are either Medaka Kurokami or Ajimu (both from Medaka Box). Which character do you think would be the better opponent?

Thanks.
