Question about RAW advantages over JPG made me curious if somebody has examples where in-camera JPEG is actually image quality-wise better than RAW image converted in computer (possibly by third party RAW converter). I don't mean default settings, but the best you can get from both.
EDIT: I finally found at least one example myself: http://theonlinephotographer.typepad.com/the_online_photographer/2010/06/iso-6400-from-an-ep1.html
Although this is really subjective, I get consistently better colors from Canon's DPP (which should match the camera algorithms) than what I get from the converters I've tried. This might fall into (poor) skill category though.
EDIT2: Another case where this could possibly happen is when the highlight rescuing functionality (Active D-lightning/Highlight tone priority/...) is used. So if anybody has made this kind of tests, feel free to share your results.
EDIT3: Here are my own results where in-camera noise reduction seems to beat everything else: http://photo.stackexchange.com/questions/2691/does-long-exposure-noise-reduction-option-make-any-difference-when-shooting-raw/2705#2705
