Both Nikon D2Xs and Nikon D300S have APS-C sized 12.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the D2Xs and D300S sensor size comparison.
Nikon D2Xs and Nikon D300S 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. Nikon D2Xs and Nikon D300S sensors have been tested by DxO and the results show that D300S has a better overall score of 70, 11 points higher compared to D2Xs's score of 59.
