Canon 6D has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic 5+ processor. On the other hand, Nikon Df has a
16.0MP Full frame (36 x 23.9 mm ) sized CMOS sensor and features Expeed 3 processor.
Below you can see the 6D and Df sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 6D and Nikon Df Cameras
Canon 6D and Nikon Df 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 and Nikon Df sensors have been tested by DxO and the results show that Df has a better overall score of 89, 7 points higher compared to 6D's score of 82.

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
or the
Nikon Df ,
including hyperfocal distance.
