User blog comment:SethHeartphilia/Whos stronger Erza or Mirajane/@comment-121.54.32.105-20140512165208

Mirajane Pros: -Has more destructive power than erza. -Demon Halphas <= Racer's speed (Reborn Oracion Seiz) -Demon Halphas has wide range of destructive power. -Demon Halphas toys with Satan Soul -Demon Sitri (we have yet to see its power) Cons: -She can't use it repeatedly/continously because it takes huge ammount of magic to use.

Erza Pros: Has over 100 type of armor which she can use at combination as seen on 1vs100 -Great phisical strenght even without armor. -Immense ammount of indurance. -Armadura Fairy Armor destroys Erza Knightwalker's strongest spear Ravelt, and "shatter an entire island". -Adamantine Armor can withstand Jupiter cannon (which I think is on par demon halphas destructive power) -Nakagami Armor able to bend the laws of magic, can easily dismantle an oponent by brute force -Holy Hammer Cons: The only weakness I can see is that she has less destructive power than mirajane.

Verdict: We all see how much destructive power Mirajane has,but erza also posseses that kind of destructive power when using the Armadura Fairy Armor. Halphas is obviously faster than Flight armor and phisically stronger than Purgatory armor but Erza has enough tricks to endure the fight until Mirajane's magic power is depleted. That is the time where Erza strikes back and win their fight.

Note: I like Mirajane more, she's much cooler than Erza :D but I admit Erza will win their fight.
