Exposure Compensation

Why? I've decided to use manual mode. Many will say that the go to setting is to use Aperture mode. Ok seemingly a good idea but you give up control of shutter speed. This may result in motion blur. Maybe for artistic reasons you want motion blur but not as a side effect. 

Ok use Shutter speed but give up depth of field. Why do you want that side effect? A Nikon eBook    says "Although it is possible to use the exposure compensation feature in the manual mode, it is more practical to use it with the P, S, or A modes because the camera will make the exposure adjustment automatically. In the manual mode, it is much easier to simply shift the aperture or shutter speed by the desired amount directly if you wish to deviate from the metered exposure."

Yes exposure composition may help but I ask why? Use Manual mode and do exposure composition by changing Shutter speed or Aperture. My camera is set so that 1 click is the Shutter speed or Aperture dials is a 1/3 stop change of exposure. 3 clicks = 1 stop.
