Vote for Ultear. Mira is overated. People think she is all that because she fights much weaker opponents and finishes the fight in one move, but put her against a more competent fighter like Azuma or Seilah and she loses. Ultear has Time Arc, her magic absorbing orb, Ice Make, ability to manipulate magic containers, enough magic power to move things of the size of the Tenrou Tree. And she had 7 years to improve her skills, which results the author of this manga in his wisdom never bothered to show.
