What are your favorite(s) MMD(s)

I like many Vocaloid MMD videos. But this one I like. It's Hatsune Miku VS Len Kagamine Sword Art Online battle. Hatsune Miku plays as Kirito and Len Kagamine plays as Heathcliff/Akihiko Kiaba. It's a great duel between Vocaloids. Cop and past the link to watch this Hatsune Miku SAO MMD Vocaloid fight/duel. ----> link
