No, there is no "one true Link", OoT Link is the only Link of his time, but WW Link is Link as well. "One true Link" is like saying there is a "One true Bob". I personally don't care what Link it is, all Links are the same (besides minor differances like hair color). Link is a silent (more or less) person who helps people out and ends up saving the world through courage.

"I must not fear. Fear is the mind killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain."
