What is your questions?
I started with digital and just started to shoot with film in 2010 [last year], and this year  i started to shoot with large format, i don't have 35mm film, only MF digital and film and now LF.
I scan with Epson V750, i agree that i prefer my digital file over film scans, and that is why i feel or say i think to get a drum scanner to have maximum quality out of the film, and i may prefer B&W film over digital, but colors i like digital more, there are films that give me different colors look that i can't get with digital, so i can't judge that film beats digital or digital surpass film, i have both and use both.
About the focal length why that CAnon has widest 17mm, in fact 17mm is not the widest lens with Canon, and MF sensor or film/sensor size is larger so the equivalent is bigger number, so 40mm on MF 6x6 is equivalent to about 24mm on 35mm format, the lens 43mm on Mamiya 7[6x7] is equivalent about 21mm on 35mm format, to me i am fine with 20-25mm focal length on MF, it will not be a big deal for me to have wider, also Lf has lenses that are coming equivalent at about 14-18mm on 35mm format [depends on what LF size].
Use film or digital for what you want, don't ask others to tell you which one is better or highest quality, not all can go with highest quality or want highest quality, i have 60mp camera and i really feel idiot if i want to have 80mp or even 100mp and don't use moor mp for what is worthy.
