Canon 6D MII has a
26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Canon R has a
30.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features DIGIC 8 processor.
Below you can see the 6D MII and EOS R sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 6D MII and Canon R Cameras
Canon 6D MII and Canon R 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.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Canon 6D MII and Canon R sensors have been tested by DxO and the results show that EOS R has a better overall score of 89, 4 points higher compared to 6D MII's score of 85.

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
Canon 6D MII
or the
Canon R ,
including hyperfocal distance.
