Ah this old chestnut , OK lets have my take on things, yes Eddie could play faster and make some great noises out of his guitar, but Page was an innovator for using the guitar as a voice to create a sound scape where as Ed used it to create jaw dropping guitar stuff !!
Both fabulous in their own way, but to me the most important thing is Phrasing, when learning an instrument, you can learn to play easy/hard chords, learn to play slow and learn to shred but when it comes to phrasing that the hard part and for me its hard to learn some of Eddies fast playing and Even more stunning to me his rhythm playing which gets overlooked.
With jimmy Page you get phrasing even from the most simple of things and to get that right takes class !! Ed's fast runs are pretty straight forward and not to much emphasise on phrasing is going on a bit like a lot of the metal guitarists of today, lots of shred but not alot of phrasing going on, but every now and then like say Joe satriani he can shred but also has feel/taste and above all his phrasing on simple bits like the opening of Always with me and Always with you is wonderful (soz to go off topic).
So for me Jim gets it for me for overall musician but Ed for coming along and showing us guitarists that there is more ways to skin a cat !!!
