Gary Moore was a magnificent guitarist but an average singer, often out of tune, and not a so good song writer. Phil Lynott, on the other hand, was Mr. Cool, charismatic, and everything he touched turned into an explosion of feelings and musicality. His voice was unique, sensual, full of soul and humanity. In my opinion, he was in the top 5 of the best singer with J. Brown, M. Gay, Marley, Peter Gabriel.
