The 80-200mm f/2.8 is a great lens, but the A/F is a bit slow by today's standards, and the A/F mechanism isn't quite as smooth as the later 70-200 versions. The 70-200mm f/4 is superb. It, and my 24-120 f/4 are my "walking around" lenses for my D750. I also use a 16-35mm f/4 which "rounds out" my kit.
When I got the Sigma, the same dealer had a 70-200mm f/2.8 VR, version 1. I'd read of a "clunking" noise when focusing, so I opted for the Sigma, instead.
