Erza vs. Mira isn't going to happen.... Although my take on the situation is that they are equal in strength. Pre-timeskip I believe it was Erza no doubt. Mira was still strong, but she's spent 2 years off the battle field while Erza was still fighting. But now that Mira has had time to train again, I think they are back neck and neck.
