Can't really address the F3MA part of your question, but I cut my teeth on an FE2 with MD-12 motor drive in my photojournalism classes in college in the 1990s. I shot everything from portraits to college football games with that camera. I didn't upgrade to the F4 until I was about six months into a newspaper job after I graduated. I still have the FE2 and occasionally break it out for landscapes. I don't think you can go wrong with either option. With that said, with the absolutely silly prices on used F4s and F5s, I'd look at one of those instead. If you want to maintain the basic manual elements, the F4 is really hard to be for the <$200 it can be found for today.
