In DigitalCameraInfo's Nikon Coolpix S630 vs Sony Cyber-shot DSC-T900 comparison, Tim Barribeau wrote:
In terms of performance, the Sony has a noticeable advantage in a few places. Its color was a touch more accurate, it had sharper images, a much better stabilization system, faster burst rates, and higher-quality videos. In the Nikon's favor are significantly lower noise levels and much lower distortion.
