Panasonic S1R II has a
44.3MP Full frame (36 x 24 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Sony A7R III has a
42.0MP Full frame (35.9 x 24 mm ) sized BSI-CMOS sensor and features Bionz X processor.
Another similarity between these two cameras is that both Sony A7R III and Panasonic S1R II sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the S1R II and A7R III sensor size comparison.

Panasonic S1R II and Sony A7R III have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Panasonic S1R II
or the
Sony A7R III ,
including hyperfocal distance.
