I don't know. Judging from the video of the doeRoscoby put on their web site and the ones I could find on youtube I think they are pretty equal.

You gotta remember that the Stealth camera is mounted to a mountain bike that is traveling at about 15 mph down a rocky mountain trail. Pretty tough for any camera to get high quality images. The videos of the Roscoby seemed to be equally grainy when the camera was moved around a lot.

Ido agree that Stealth neeeds to get it on their web site and post some hunting video for us to view.
