Maynard from Tool is probably the best metal singer in the world at the moment, and that's almost an objective opinion amidst metal heads, at least around my area anyways even if someone doesn't like Tool, they give the guy his props where due.
who ever hates on chester is an idiot. he can out sing any body u ever hear any covers hes done blows the origional out the water

I don't like their music, but like Maynard, have as good scream and a great and different sounding singing voice. You always know it's him. Other favourites, but not the best are Akefeldt, Jonathan Davies from Korn (again, music not great anymore but the guy is unique), Jonas Renske, Devin Townsend and Mike Patton. A list basic on individuality IMO
