Here's the thing, the Floyd had three sounds, the original, the evolved one they got to about Atom Heart Mother or so, and the third one after the Final Cut when Waters left. Superb band across all three, however, the "Pink Floyd Sound" (one of the earlier names of the band as well), was the second, evolved one. That sound needed both Waters' singing and Gilmour's guitar. Yes, Waters played bass, and Gilmour did sing, but Waters's vocals are iconic and so are Gilmour's guitar solos.
I need them both. I do like the later work of the Floyd, and I do like Waters' later work, too, but, to me, the band became something else after the Final Cut, which is really The Wall, LP 3.
The world thinks the best album is Dark Side of The Moon.[...]
