Leica M9 has a
18.0MP Full frame (36 x 24 mm ) sized CCD sensor . On the other hand, Canon R6 has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor.
Another difference between these two cameras is that Leica M9's sensor lacks anti-alias (Low-Pass) filter. 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 M9 and R6 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M9 and Canon R6 Cameras
Leica M9 and Canon R6 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Leica M9 has 10% larger pixel area compared to Canon R6, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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. Leica M9 and Canon R6 sensors have been tested by DxO and the results show that R6 has a better overall score of 90, 21 points higher compared to M9's score of 69.

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
Leica M9
or the
Canon R6 ,
including hyperfocal distance.
