I can't compare Hendrix vs. Evh because they are two different styles.
Hendrix was Blues with Soul, Eddie plays mainly Major voicings (happy sounds), but would slightly flatten his B string to avoid the rapid beating of the Major third through distorted Amps, giving great opportunities with open G and B string interals. He also built his own guitar that became known as the "Frankenstrat" and as heavily involved in the design of the new Floyd Rose locking Tremolo system. Through trial and error he became the main influence for Floyd Rose and came up with adding fine tuner knobs to the system. He then invented the "Detuna" system by allowing the low E string to be dropped to D tuning with the flip of a knob and pioneered the "Transtrem" system that instantly changes tuning by 2 1/2 steps (used in the song "Summer Nights" for instance). He also created his now famous "Brown Sound" with amp mods (although never admitted ) by reducing wattage to his amps. All of Eddies "bag of tricks" make him one of the most influencial guitarists of all time. He has drawn most music manufacturers to his doorstep in hope that he would endorse their product.
Like him or not, EVH is much more than a guitarist, he is an icon in the music industry.
By means of a guitarist, Jimmy Page has incorporated more advanced voicings to the industry than most.
Hendrix, RIP, died over 36 years ago. Just imagine what he would have gifted to the music industry by now.
