I think they are pretty even though mira may have less experience of 3 years, though mira has not been given a good enough fight to judge. Also, being rivals as kids, Mira probably has forms that can counter Erza's armors. I would not be surprised if she can do at least 10 different take overs.

Would be awesome to have a battle to see though.
