Shooting in a higher bit depth ALWAYs results in a better end image. When you compress in camera you get a lower color resolution and color noise cause it does it in real time and does it poorly. When you compress after at the end of pipeline the effect on image quality is not noticeable in HD or above quality. Compressing in camera kills the image recorded cause it compresses sensor data as it gets recorded so you lose a bunch of data. Compressing at the end does not lose data it just cuts out data that isn’t needed.
