Since DXO, my preferred RAW converter, isn't really ready to work with the mk3's RAW files, i've been shooting more jpgs than i have in years. i've been impressed with the mk3's jpg engine. If the exposure is good, and the WB suits you, i really don't see a RAW file making much of a difference. That said, once DXO has a handle on the files i'll likely go back to mostly shooting RAW for most everything but there are surely times when i wouldn't hesitate to shoot jpg. Confusing, isn't it.
