Those are F2SB models and are essentially the same metering as the F2AS but for pre-AI lenses.
I’ve never had an F, but if I got one I’d want the unmetered finder. I have an F3 and F4, but never really use them. My collection of AI lenses is far more limited than my pre-AI.
All great choices. I sold nearly all my Nikons (i've had F, F3, FE, FM, FM2, EL, EL2, Nikkormat FT2, FTN, EM, FG) and kept my F2AS and FM, although the latter will be replaced by a FE one day.
Indeed the F is easier to use with the unmetered finder. I always thought it had the best shutter noise of all Nikon cameras except for the mechanical Nikkormats, which really have a satisfying sound.
I also prefer pre-AI lenses, that's where the Nikon soul dwells.
