I have a Canon EOS 10s (3 AF points! Haha!) and was using a Canon EOS 1v (last 1 series film body they made, pro film body, etc.)...
The 10s is really just light and fun for basic stuff, I take it with me when I go out for coffee or with the girlfriend somewhere cool, or just with me in general, usually with the 50L on it. The focus is fine in daylight, but if it's pretty dark, then the AF sucks bad, and manually focusing isn't too accurate on it.
The 1v, I shot a lot of documentary work in Cuba, 3 trips altogether over the last year, the 1v was a blessing for that, the AF was better than my Mark II, and really snappy, but not perfect, of course since it's an older AF. But it was great, and obviously built like a tank, and had lots of pro features (for a film body).
Personally, later this year I'll get a Mamiya 7ii (6x7 in a range finder! Haha awesome), and a really tiny rangefinder, like a Canonet or something. I don't like 35mm film too much to be honest, 645/6x6/6x7 is really where it starts getting "Sexy".
But what I mostly use 35mm film for, is what I mentioned above, especially just going out with friends, coffee, walks, bike rides, whatever fun moments (like at the fair, or festivals and such), I shoot about a roll of 36 exposures every two weeks, and just go get it printed, if I like a few of the shots to show on the web, I'll just scan the print. It's really fun, and to be honest it makes me feel good to take all those shots, sorta forget about some of them, get them printed (that's neat) and have them to physically look at. It's a fun way to shoot lots of film without any pressure.
But my main passion is medium format film for portraits. My 645 and my 6x7 are my babies. I love them, dearly. I use them about once a week or so.
