I've made the same comparison of MM vs. A7rII (with a thin cover glass conversion, which mostly, but not entirely, solves the "smearing" problem with Leica wides). I concluded that I prefer the MM look. Resolution is similar but I prefer the MM files, which seem more film-like to me. The A7rII is challenged by the Leica wides and I'm primarily a wide shooter. I generally shoot with medium yellow filtration in front of the lens on the MM which gives me tonal values that I consider attractive. I do print large (24x36) and the MM files are up to the challenge without heroics in post.. . .
For landscapes I've recently switched, however, to Sony A7rII bodies (standard, and Kolari mod), still using mostly my Leica lenses, because after quite a bit of testing I decided my Sony BW file conversions are of equal quality to my Monochrom files. And IMO it's a considerable advantage to be able to use the color conversion sliders in PS to rebalance the tones in a BW image. That's usually the last thing I re-check before making a print.
. . .
I'm using the A7rII primarily for legacy lenses (Carl Zeiss Contax lenses from the 1930s-1950s) and specialty lenses (Canon TS), and in a few cases, away from the mainstream of my work, where I need autofocus.
These really are matters of personal preference.
