I have both of those. The Sony is way better. GoPros are great for doing things that might destroy the camera, or where you need a really small unit. In terms of real photographic quality, they are near to shit (horrible barrel distortion). If any of your shots are interior or in an area where there are strong horizontal or vertical lines, they will look like they are bent. Plus the Sony has a threaded collar at the end of the lens which enables you to get adapters for different looks. Neither camera is really up to snuff when it comes to manual control of the camera, but the Sony comes closer.
