What everyone should be asking themselves is, "Do I enjoy listening to Kirk Hammet's guitar?" His talent is irrelevant. The joy you receive from listening to him (or lack thereof) is what counts. I think Benoit's signature says it all:
"The greatness of a guitarist is not based on how many different techniques he mastered but on how much joy he gets out of playing."
I just think that we shouldn't lose sight of this point.
