While there may be a limited number of people use stuff simply because of artist endorsement, my experience managing a guitar store is that the endorsement encourages people to TRY something. D Addario does not sell a crap-load of strings because Wooten, Willis, Metheny, et. al. endorse them. They sell 'em because people like them.
From managing the store my experience is that D'Addario is the most consistent string company, and great service to both the retailer AND the end-user, and had a focus on waste reduction in the '70s.
I use only D'Addario on my guitars, both electric and acoustic for those reasons. I'be used other strings on basses (notably GHS, DR, TI, and Dunlop for extended periods, and again find myself coming back to D'Addario . But the point us I use them because I like them, not because anyone else does.
Another important consideration is, as Jimmy M has said, individual body chemistry strongly affects string choice.
