Both Canon T6s and Nikon Z6 II have 24.0 MP resolution sensors but Canon T6s's sensor is APS-C (22.3 x 14.9 mm ) and Nikon Z6 II's sensor is Full frame (35.9 x 23.9 mm ).
Since Nikon Z6 II'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 T6s.
Below you can see the T6s and Z6 Mark II sensor size comparison.
Sensor Size and Resolution Comparison image of Canon T6s and Nikon Z6 II Cameras
As seen above, Nikon Z6 II has a 2.6x Larger sensor area than Canon T6s. 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
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 T6s and Nikon Z6 II sensors have been tested by DxO and the results show that Z6 Mark II has a better overall score of 94, 24 points higher compared to T6s's score of 70.

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 T6s
or the
Nikon Z6 II ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus Full frame),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
