You guys dont even know what your talking about, MUSIC is ART its not about whos the Best its whos the most creative, not whos the fastest or technical. Its who touches us the most.
Just like drawing or painting, music is relative to the person that is hearing it. NO one is the best, even a beginner guitar player can be a genius to another.
EDIt: And I dont believe being taught guitar is the best way to learn its the best way to mimic someone but not to learn. Being taught guitar is the fast way to learn, but self taught guitarist are overall better players. Taught guitarist will never have there own thinking patterns, self taught ones develope there own and are more creative.
