Speed: I agree that Laxus has the edge here, though I think that speed would play a huge factor in the fight given the fact that Laxus isn't solely focused around out-speeding his opponents, and the fact that Erza does have her Flight Armor.

Power: I agree that Laxus also the edge given that he is quite physically strong and that he does have a large amount of Magic Power. Though Erza has a pretty good amount of Magic Power herself, we've never seen her display the amounts Laxus has obviously, but she does have a sizable amount and she is very physically strong as well.

Endurance: Agreed, though I think that Laxus might have a large amount of endurance himself, but we haven't seen him in nearly enough situations where he can display the trait since he's not a main character.

Tactics/Strategy: Agreed.

As I said earlier, I definitely believe that Laxus is the stronger fighter, though I don't agree that he's way stronger. I think that if him and Erza were to fight, it would be a pretty close fight with both suffering some costly damages, butt he would ultimately come out as victor.
