I have to call you out if you think Lifeson isn't deserving of many accolades, especially in light of those you named (Johnny Cash? Seriously? If you are going to bring him up how could you not mention Luther Perkins who handled most of the heavy guitar work?).
His phrasing and chord selection is quite unique when compared to most other players. And while his solo's don't tend to be the shredding type, they have their own distinct qualities and add to the songs rather than being some excuse to noodle over some old and tired chord progression.
