I would think of imaging as broken out into three very high level categories.
Consumer, Commercial, and Industrial.
For consumers it is mostly about nostalgia and a process that is enjoyable to use.
For commercial (I am including high level hobbyists, still professionals, cinema, etc) there are technical advantages such as the size of the image produced (film area vs digital sensor area) and other factors which have a meaningful impact on the final product.
For industrial (I am including things like research) there is no (cost effective) digital equivalent. I remember reading about an experiment where they would fill a chamber with large blocks of film, and then track particle paths through the film.
You can go super deep in each area to find the technical differences that people in each one care about.
