Yes, it is. And strangely, Carlos Santana is missing, too! For me he's one of the best 3 of the present (MK, Gilmour, Santana). There are so many who are maybe even better technically, but for me it's the tone, the soul, the touch that make the difference.
I think, MK is often underrated / overlooked because a) he doesn't fit in any "box", with his unique technique and many different styles, and b) he's too "normal", scandal-free, normal-looking etc. I'm not sure whether Jimi, Keith and a few others would figure so prominently if they or their bands hadn't set guitars on fire, killed a chicken on stage, demolished a hotel room or whatever else rockstars do all day long ;-)
