O. K. this will probably sound weird, cause I see noone mentioned the guy yet, so you probably don"t consider him a good guitarist, but...
Steve Stevens, Billy Idol. I like him a lot. He may not fit into the originality category, but hearing his live performance, he is definitly at home in craziness
category... at least to me.
as for else:
Feeling-Slash
Speed-Yngwie
Songwriting-Izzy, Hatfield
Originality-? Hard to judge. Van Halen??
Heavyness-Iommi, Murray
Slide-Chris Rea, Cooder, Stevie Ray
Blues-Stevie Ray, Clapton.
