Both Nikon D3300 and Canon M6 have 24.0 MP resolution sensors but Nikon D3300's sensor is APS-C (23.5 x 15.6 mm ) and Canon M6's sensor is APS-C (22.3 x 14.9 mm ).
Since Nikon D3300's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Canon M6.
Another difference between these two cameras is that Nikon D3300'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 D3300 and M6 sensor size comparison.
As seen above, Nikon D3300 has a 1.1x Larger sensor area than Canon M6. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
Both Nikon D3300 and Canon M6 sensors have been tested by DxoMark.
