Personally prefer shooting JPEGs because it offers the closest feeling to actual film in that you don't have much room to save the pic if it stinks due to various reasons. Unlike RAW where you have almost total control over how you want the end prouct to be, in JPEG you take it and that's pretty much it, since there is limitted PP to be done on it.
Besides, with the amount of time spent on attempting to correct a RAW in PP, the JPEG user would have already fired off a ton more shots and has a better chance of finding something almost usable right out of the camera with minimal touching up required. And when you are doing reportage or journalism, RAW is essentially a no-no unless you can be sure that your single RAW shot is the perfect shot you need.
