Good comparison - I respect David Sanborn. He plays what can be considered 'smooth jazz' or 'adult contemporary' music, both fair assessments. He had a cool late '80s musician-centric TV show hosting many jazz heavy hitters - he was a contributor to his craft and a champion for broadening support for music. KG found his star niche and many, many people liked him enough to make him quite wealthy while other more talented musicians just get by. Never having been put in that position personally, I wouldn't know what that's like, and who cares? More power to him.
