Both Canon 760D and Canon T6s have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the 760D and T6s sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 760D and Canon T6s Cameras
Canon 760D and Canon T6s 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.
DxOMark Sensor Scores
At Camera Decision, we also look at Dxo Mark sensors when available as we think it is a good indicator of image quality.

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 760D
or the
Canon T6s ,
including hyperfocal distance.
