User blog comment:SethHeartphilia/Whos stronger Erza or Mirajane/@comment-26437512-20140418102432

I'd say Mirajane is stronger, she's pretty much defeated all her opponents apart from Azuma, she lost the battle with Azuma because she didn't have enough magical power and she was given a three minute limit to beat Azuma which even Erza wouldn't have been able to do. I think Mirajane would have defeated Azuma if it wasn't for that time limit. And for those saying that Mirajane and Erza would be useless without their Armour/Take-Overs that's true but keep in mind most characters are useless without their magic.
