In my opinion, it just doesn't make sense comparing a tenorist to a falsetto artist be it singer or animator. Bill should be compared with Kerozene, Genta Lissimo, Djouna Mumbafu, Acide etc and Brigade should be compared with Celeo, Kunzardo, Blaise Createur, CNN etc. The style of animation of tenorists and falsettos is completely different, tenorists usually sing whilst falsettos speak randomly sometimes in a melodic way.
I agree, and even mentioned it that the two styles are different. But fans views are sometimes stronger than style (because some of them don't know any better). But at the end of the day, popularity is paramount to stay on top. It's just that right now, the people are giving it to Brigade.
The fact you're defending Bill says it all .I used to defend Hercules but now most have caught up; this guy can light up any audience.
