I have Nikon F, F2 and F3 cameras sitting on a shelf right behind me. If I ever got the notion to play with film again, I'd go out and find an FM2.
Pros could configure an F3 to do whatever kind of work they did. Every accessory Nikon made had a version that fit the F3 and a lot of them only the F3. You had your choice of finders, screens, meters, backs, motors, whatever. I built mine for speed. The MD-4 motor was what I liked best about it. Plus it was bulletproof and I beat the crud out of mine. If you go with an F3, get a beat up one if you really want street cred.
But I always carried an FM2 as a second body. Much simpler but no less competent. If you don't use an F3 every day, you'll have a hard time getting comfortable with it. Mine scares me now. And don't worry, you'll get your retro cred with an FM2. It seems to be coveted by the film crowd now. They're hard to find and pretty expensive compared to other SLRs - even F3s. I've looked and I get it.
I got into photography in high school and learned the craft on broken-down swapmeet SLRs. I learned, in that world, never trust the meter. I got an incident meter early on and never really learned to work with a camera meter. With an FM2, I'm pretty sure the only thing the battery runs is the meter. If you have film, you can take shots.
I don't know what an EOS 1-v is.
Edit: I was just thinking. I sold my last FM2 and my 180mm 2.8 and bought a space-age Nikon 8008 and an autofocus zoom lens. Worst trade of my life. What a piece of dung, that 8008. That's the last film camera I bought. Is that anything like a 1-V?
