On the specific subject of Monochrome fine art , from personal experience I would have to say Digital has now surpassed film, mainly due to what can be achieved from a RAW file through to completion in Photo Shop. It would take a highly skilled darkroom person with years of experience, to be able to emulate what someone of medium Digital skill can achieve these days in PhotoShop.
I see this as a positive for Photography as a whole, as it has allowed people like myself to start producing reasonable shots on a regular basis, that I would have struggled to do the same with film.
About 20 years ago I tried the whole darkroom setup, desperately trying to get the dramatic monochrome prints showing deep blacks through to clean whites.....but to no avail. I then left photography for about 15 years, until Digital gave me a glimpse of hope to get what I wanted
Now don't get me wrong from all the above. There are some excellent photographers out there who create incredible prints from film, but I would say I have seen more decent images coming from Amateur Digital users these days, than film users of say 10 years ago.
Just a personal view of course
