Thing is, there is no specific set of guidelines. If you want raw ability to play, then it has to be EVH, Vai, and Satriani. If you want pioneering sounds, then Hendrix, Paige, and EVH. If you want the music writing ability then Gilmour, Paige, Rothery (of Marillion), EVH (yes, again), and Clapton.
There are many great guitar players. But if you want an all inclusive list, I believe EVH is at the top. Who has done what he has all across the board?
