I don't like to compare, but here are two guitarists I believe are more technically and musically accomplished than pagey.
This guy's playing is so unbelievable. Listening to him is like elevating yourself beyond reality. It's a blend of so much and so unrestrictive to formats. His rythm part is like his solo part, and vice versa. There is so much in his playing, it's beyond just playing something to a chord structure. The little notes he adds here and there can change so much about the song.
A modern genius. Just because he did not play in the 60s or make some big name from a world famous rock band does not mean that he is any less than the gods of rock. His music is much like hendrix's- without restrictions, without boundaries, and at times without a sense of intention. It's free flowing and it just works like that.
Pagey is great, he has a great sense of direction and melody, and his riff writing is some of the best.
Again, music is subjective, of course. Some people could even consider Raffi to be a "better" guitarist than Brian May.
