Which photo looks better? I will leave final verdict to judgement of audience
The RAW post processing shot looks better to me because the Jpeg has too much contrast which darkens the photo and loses detail but you can adjust contrast in-camera. 8 bit jpg has 16 million RGB colors total whereas 12 bit RAW has 68 billion total however it is hard to see any difference in these photos because of the lack of variety of colors. I have noticed that I can pull more colors out of a RAW file than jpg. I agree that jpg are sufficient if you are going to just post photos on the web.
