Yeah, I had two F4s as well as the F100 and sold those off even though I really liked them. I decided that the F6 met the ‘pro’ requirement while the N/F80s met the ‘camera you will actually use’ requirement!
I liked the F75 I had but the feature set was just better - without being too much - on the 80 plus the 80 felt like the perfect compromise between build quality and weight.
Nutty thing is the F/N75 often is more expensive now than the 80! The 80 has a bigger and brighter VF, the amazing focus screen, you can set meter patterns no matter what mode you are in - the 75 you had to use custom functions eg I think I had spot set to work with focus lock IIRC - much better dampened shutter, bigger shutter speed range etc.
I’m sure Canon, Minolta, Pentax have equivalents just as good. I just happened to already be in the Nikon ecosystem.
