I think Mira is magically stronger. She chooses not to use her magic against guild mates. She said she won't use her full power on her friends ever. She got most of her magic back and Erza even with 2nd origin couldn't defeat Curse. It's not magic. If Mira got 2nd origin and used it at its full potential, the universe would blow up. She accidentally destroyed a city in Halphas, not using its full powers. Erza is down to like 2 armors in her 1 hour long fight, gives the friendship speech, and somehow wins. Mira barely even breaks a sweat.
