GiX, impressions of RAW vs.jpeg

G1X users, I have been shooting in RAW with Ricoh cameras and RAW makes a difference to my eyes. Now I know with some cameras the difference may be negligible and for me, a person that does not do much PP, some tweaking of sharpness, contrast, a few other little things...what are your impressions of the jpeg engine, and how much more if any do you believe you get from RAW?

Thanks
