I actually agree with DaveyJ's remarks.
In my average situations my first inclination is to under expose to keep highlights and let the darks go dark. What SquamishPhoto is talking about with mixed or low light, I always shoot Raw. If there is fast movement that I'm shooting, it is always Raw. Probably 90% of my photos are Jpeg - more so because I like the Nikon color and settings I have.
Here is my personal distinction when I shoot Raw: I generally underexpose 1/3 - 2/3's a stop. My D300 is almost always about 1/3 under anyway so I can sometimes get away with a full stop. With Jpegs I can fill or bump the exposure that small amount no problem and shadows come back easily. If my over/under exposures exceed more than 2 stops either direction, I shoot raw.
All of us shoot differently. Personally I watch exposure and histograms non-stop and rarely have a file I can not work with. Working with a file, takes me less than 5 minutes and I rarely ever have to move out of Lightroom. It works for me.
Raw is easier to edit for sure. My edits, are rarely that extensive, so Jpeg works most of the time for me. There is a reason why there are two settings. I just tend to use both, with one more than the other.
I am rather baffled why anyone really thinks there needs to be a debate here. It is just two tools in a box.
