I] Good solo Erza wins (imo):

1. Eisenwald goons. (Not counting Lucy's share)

2. Angelica.

3. Phantom Lord goons. (Not counting everybody else's share.

4. Aria. (Only because it was one of Erza's earlier one-shots against a hyped opponent, if it had been one of the later ones, off the list.)

5. Ikaruga. (Good character development here too. :P)

6. Evergreen.

7. Midnight. (My favourite Erza battle. :P)

8. Erza Knightwalker. (Good one. Liked it. And Erza's reason for the win.)

9. Juvia and Lisanna.

10. Grimoire Heart goons. (Not counting Juvia's share ... Is this in the manga?)

11. Pandemonium.

12. Jenny Realight.

II] Bad solo Erza wins (imo):

1. Azuma

2. Kagura

3. Minerva

4. Neo-Minerva

II] Wins in battles which were interesting (imo):

1. Aria.

2. Ikaruga.

3. Midnight.

4. Erza Knightwalker.

5. Azuma.

6. Pandemonium.

7. Kagura

8. Minerva

9. Neo-Minerva

Now, the combination: n(I] U III]) == 5 n(II] U III]) == 4

Didn't include Juvia and Lisanna, Evergreen in 'Interesting' because, basically, they were not. Outcome known is not interesting. Was iffy about Pandemonium, was actually iffy about seeing it as a battle, but still included it. So ... right now, Erza is ahead by one on my list, but the trend is painfully visible. And Aria is only on good list because it was one of Erza's earliest one-shots, just like Tempesta is Gray's. But, then, this is all my opinion. :P

I need to stop making these long responses. >.>
