I love you. I would add Gumi to the list, though. For males, I like Gakupo, VY2, and... Mikuo, which is surprising because I don't like Miku much. I guess the timbre of Saki Fujita's voicebank just sounds best in the boyish tenor voice range?
On the other hand, the new V3 voicebanks almost all sound really good, and in fact most Vocaloids have the potential to sound good with the right producer's tuning.
I think it goes without saying that my first really big Vocaloid ensemble project still makes Luka the center of the story.
