I seem to be in a minority here (nothing unusual!) … I bought the K-3iii as a "a/f upgrade", knowing full well I'd miss the fully articulated screen on the K-70, but as I wasn't trading it in I'd have that to fall back to when necessary.
I also have the Ref A right-angle finder from my film days, which has always come in useful, when necessary, on all my cameras.
One of the problems of increasing age (as many are probably aware) is the lengthening of the closest distance one can focus one's eyes unaided.
Struggling to read the detail on a rear screen is one reason I continue to prefer an eye-level viewfinder.
Weirdly, I rarely use the tilt screen on the KP and I'm really not sure why
