Gackt, because his song are different and still good, but i think that HYDE (or with luruku) is doing still similar music.
Anyway, I like them both very much, but you know, Gackt is Gackt
I think that more people would like him without make-up. OMG people, don't look on image, but on behavior and inteligence
And Gackt sure is good and very inteligent and educated guy!
