The only rf I have with AE is the Canonet and the Olympus SP, oh, and a Petri I seldom use.
My first AE was the Fujica ST901, which has AP. I quickly learned to appreciate that very much. It was quite accurate, and I knew when it might not be so I could compensate. What I really like about it was for crime scene processing. I might have to search for a correct shutter speed with SP, but with AP I could just compose, focus, including DOF, and trip the shutter. It was the same with the Contax 139Q I had, although it would not make as long exposures. However, its otf flash was superb.
However, using my Press 23 or my folders, or anything else without a built in meter, like the Kiev, I use a light meter without feeling bad. It's just the way to do it.
