Is Sinon または Asuna better?

Well, we haven't seen them fight each other but based on their weapon choice and the battle with Zekken (Yuuki), Asuna has a better chance of being stronger.

Fans~
If あなた talking about who has もっと見る fans, then based on MAL, it seems people seem to side with Sinon when it comes to polling. Though they do, when it comes to favorites, Asuna wins によって quite a lot.

Conclusion~
It actually just depends on the individual's opinion.

Well I personally would say Asuna cause yer know shes cute and pretty good with that sword of hers but,

That's just my opinion personally I like Asuna Yuuki
But ya know its my opinion

Well, I think it depends on the conditions. If it is a close range battle または hand to hand combat then asuna is better but if it is a long range battle then sinon has a higher chance of winning.

Asuna because she was known as the lighting flash asuna which is a diffcult タイトル to claim while Sinon is a just getting started to ALO and stuff.In GGO sinon isn't as powerful.She got shot with a silent bullet I think and was about to get killed.If she stayed on guard she could of noticed the bullet sooner.Asuna is sorta もっと見る powerful that Kirito when she fought Yuki in ALO.Yuki accepted her into her party.While she could of gotten kirito.So that is why I think Asuna Yukki is better than Sinon

Sinon is the best
