I prefer the high rise shutter button, as well as the shutter speed dial. It's why I also have the AR-1 extended shutter release button on my Fs and F2s.
What I don't like is the mushy rubber covered shutter button, which is why I much prefer it with the MD-4.
I packed 2 F3s with MD4s plus a third F3 with a Forschier Polaroid back for a lot of years. Add to those, about 7-10 lenses, some heavy, and a bunch of lighting and gaffer gear. I was happy to dump the motors. Most of my color is digital, and those cameras are bigger, plus batteries and spares.. and other stuff that is a pain in the back. I mostly use a single F3 plus a 35 and 28, film in a small bag or in my pocket.
No motors.
You have me remembering .. lenses: 15, 18, 24, 28pc, 35, 55micro 2.8, 85 f1.8, 105 2.8 micro, 135 2.8, 180, 300 2.8, 400 5.6, 500 f8 cat, 1000 f11 cat. I did 90% of my work with the 35 and 55 micro. Next most used were the 24 and 105. I almost never used the 15. The two cats were bought for specific work. Same with the 300 2.8. I did use the 180 and 400 for a lot of personal stuff. Way too much gear.. oh, and I had a zoom for a while.
On most jobs I took the 18, 24, 28, 35, 55micro, 105micro (or 85) and 180.
