^....and Zasetsu Chiten.
IMO, both Kuu and misono are great artist. I tend to like Kuu more because her style of music is what I enjoy listening to. Misono isn't diverse with her music and the last time I look Rock isn't a huge thing in Japan that much anymore (with the exception artists whose been around for a long time now). I must admit that I only like a hand full of misono's music compared to Kuu. Also, misono has horrible fashion sense. No one would really want to look like her or wear the type of clothes she wears. Fashion was a key thing to Kuu's success as an artist as well as style. People like the fact that Kuu brought something new to Jpop. Misono just needs to re-establish herself and her music and maybe one day, her music will be likeable to the Japanese public again.
