Do u think that Edolas Erza and Earthland Erza are equally powerful??If not, then why?????

Nope, Earthland Erza is stronger because she has the power of feelings. The power of feelings is the equivalent of having a Sharingan in Naruto. If Ты have it, Ты can overcome any opponent and winning is almost a given.

I think someone created a Опрос on this, Anyways Earthland Erza is just that bit stronger, if u talk about right now, Erza is wayyy stronger now, since she has improved and Knightwalker has Остаться в живых her magic, but if u meant at the Edolas arc, then they seemed to be evenly matched, but this IMO opinion was because Titania Scarlett was fighting to match Knightwalker, she has еще armour and could have made the fight go at her pace and not Knightwalker's . So based on that i think Titania Scarlett is stronger but not by too much. But worst case scenario, they are equal.
