My opinion on Eddie and Yngwie are that they came out of nowhere with something new and brilliant but never progressed as years went by.

Versatility wise I think Richie, John Norum, Slash are the among the best out there. But since they have been tremendously successful, they don't get the credit they deserve.

Obviously you have to nod your head to Clapton, Page, Hendrix, Beck for all they did for the guitar.
