Who is the best vocaloid in your opinion? Well I love IA, Neru and The Kagamine Twins!

Uh.
YV1V4!!!

GUMI AND FREAKING OLIVER.

I like Rin the best since she was the first one I saw and I'm just setimental

Oliver! He is an awesome English vocaloid with a high voice. He has a bunch of bandages, some of them covering one of his eyes, and a bird named James. He mostly sings dark or creepy songs. The first song of his I heard was Addiction to Pain. Whoops, I'd better stop now or I'll keep going until I put down everything I know about him ^.^U

Cul cuz her voice is so different and unique and not like all of the other vocaloids :)

My favourite is Miku, and I also like Gumi

Miku,kagamine twins,Kaito,Haku.

Miku or The Kagamine Twins

Really, the only ones I know, are the original and main ones.
Hatsune Miku, Kagamine Rin, Kagamine Len, Kaito, MEIKO, and Megurine Luka.
Out of those, my favorites are the Kagamine twins (at least I think they are twins) or Hatsune Miku.

I don't really know any other Vocaloids, soo... ^-^U
