The answer to RAW vs. JPG is it depends. If you're serious about your photography you want as much information as the camera can possibly capture and without any compression artifacts. If you are only a casual photographer a most jpgs will give you all that you want to record your memories. It's that simple.

As for post processing the point is moot. The camera does it's own interpretation of the scene in how it renders it so really there is no "right" rendition.

I see a landscape different than you or the next person. Put us all at the same place and time with our different equipment and you will get as many versions/interpretations as there are people.
