I dont think it's fair to compare any guitarist to Gary Moore. He was unique in his intensity, and to me was the most "musical" for want of a better word of any blues guitarist I ever heard. Maybe due to his rock background.
It's all a personal thing because (and this will rile some people) When I listen to eric clapton play, I feel nothing. I'm impressed with his technical ability, but his playing doesn't affect me emotionally like gary moore did. And yet we all no he's one of the greats. So each to his own and sorry to all the clapton fans.
