WAY too hard to compare. 2 totally different types of music in different eras. But I would choose Megadeth because I am not a fan of some death metal vocals.
I agree with XCoheedX. I thought high-pitched screaming and death metal vocals were the same thing. If they are different then would you please explain how?
Ok I will explain... Death metal vocals are much more like growling and shouting and black metal (I assume that COF is black metal) vocals are more like high-pitched screamings or just screaming. I hope that you understand what I mean.
