I struggled to find a comparable image for 35mm, but here's a good comparison of tonality with low-resolution scans on a small-scale reproduction: (i.e., your screen):
35mm (Nikon 50 1.8, HP5)
6x6 (Bronica 80mm on SQ, also HP5)
Click through for larger. But while the first is a more interesting image to me, the second just has a much smoother tone in the skin, and a lot more spatial separation (especially in the other images from that roll. You can't really see much grain in either. Both were lab developed (wish I knew what chemistry they used!) and lab scanned, and nothing done in post here, not even levels/curves.
However: for my sort of photography, I generally can't get a lot of strangers on the street to sit still long enough for me to focus and meter, or don't want to carry all the crap, and just plain have a problem focusing on a ground glass without my glasses.
Like Pioneer, my MF camera is beat up and held together with duct tape, but the images, provided I catch them in time, turn out with effortless technical quality.
As for digital, scanners are a rare and expensive bird. I'm personally considering repurposing my Nikon for a macro-copying of my 120 slides.
