Sensor Size and Resolution Comparison image of Canon 300D and Canon 350D Cameras
Canon 300D and Canon 350D have almost the same sensor size so none of them has any significant advantage over other in providing control over depth of field when used with 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 300D and Canon 350D sensors have been tested by DxO and the results show that 350D has a better overall score of 60, 5 points higher compared to 300D's score of 55.
