I guess I'm late to this party. I started with a Nikon SP, then went to the F, and now still have one of my two F2's (I gave the other away to a friend). When a co-worker offered to sell me his F4 kit, I bought it, and used it "forever" until I got caught the "digital bug". I went through several D2 cameras until I got one that worked, and then got a D3 for way too much $$. Since then, I've moved on to a D750, and also a Df which I love.
I got the bug to shoot some more film, and stared with my 60 year old Leica M3, and M2. A few weeks ago, I dug out my F4, and love it as much as the day I bought it.
As to "looks", two thoughts - first, "beauty is in the eye of the beholder", and more importantly, "form follows function".
People hated the looks of the F4, but all the professional digital cameras look that way. The F4 had that look "before its time". The camera itself though is wonderful. Overall, I prefer my Leica M3, but the F4 is lighter, smaller, quieter, and Leica lenses (in my opinion) can't be beat. But to just go somewhere and take photos, the F4 is probably "better" for me. As to the weight, coming from a D2 and a D3, I'm used to the weight.
