King Diamond has a very powerful, wide vocal range and performs a multitude of different styles with a pretty high level of technical versatility. He sings anything from a very advanced operatic style, to a lower, more throaty and aggressive heavy metal vocal style. I'm going to assume that you find his deliberately comic falsetto vocals annoying, but Chuck Schuldiner's most competent attempt at singing is a painfully shrill, out of tune rendition of "Painkiller" by Judas Priest. Other than that, there's really no grounds to compare the two of them, and King Diamond clearly has a more mature, fully-formed vocal ability.
The Sound of Perseverance was clearly written with the vocal performance taking on a more prominent role than previous Death albums, which is exactly what I said earlier despite your inability to comprehend it. I'm not sure why you can't understand that.
I don't like the album, and I've explained why in great detail by this point, but you have yet to do anything other than insult me and, for some weird reason, talk about King Diamond as if he has anything to do with Death or death metal as a whole. If you are so passionate about Death and this album, you can try actually talking about the album and replying to the points that I've made here.
