There are different parameters within which to rate a guitarist.
Some guys are technical marvels who cannot creat anything worthwhile. There are cats who can copy others to a T. And some players are not technical monsters but can create/write memorable music and riffs.
The best of the best are monster technicians who are hugely creative and also have a unique voice in their style.
Like him or lump him, a cat like Edward was an extraordinarily rare breed of musician.
No one is “better” than Steve Lukather.
Just a couple examples.
