For me digital cameras seem like an extension of computing, which is my other hobby, and also my job. That means digital seems old hat to me, and also I just see all the silly design problems and gimmicks that are so common in computing now.
Also, I don't like chimping, not just from me, but others, who want to take a look at the back of the camera after each shot, film solves that.
I like the look and feel of film, I like the great colours compared to digital. Sure, you can achieve great colours on digital in post, but I spend enough time on computers as it is.
I find it easy to get all the film/equipment I need buying online, it's vastly easier to get unusual stuff now that it was 15 years ago.
Film camera tend to be so much better designed than digital, I mean, it's common now to have cameras which don't even have a finder! Simplicity of operation came before gimmicks/modes.
I like the slight unpredictability, sometimes I'll take a shot and be surprised/pleased with the results on film. Digital can surprise too of course, but it's short lived, not drawn out over days. Bluntly, I like the delayed gratification.
Medium format. If I had to only shoot one format, it would be 120. You've got to spend $10,000+ to rival a $600 film system in MF, even then you're plagued with noise in long exposure.
The benefit of digital is low ongoing cost (with the downside of high initial cost), and convenience. Neither of those things appeal to me greatly, so I won't bother with digital for the moment.
