Hendrix in my opinion is extremely overrated. Yes he was very influential, but in my opinion, had very little style and technical skill. Yes he put "soul" into his music, but its just like it was mostly slop and noise.
Of the mentioned, SRV is probably the most soulful player, but EVH probably has the most style and skill combined.
There are too many means of rating guitarists, so its really not a fair question.
