In my experience, JPEGs in EOS cameras are low compression and preserve most of the image information. You can do radical tonal and color corrections on them using curves in Photoshop, and still the result will look very good. What you will not get out of JPEG are a little bit of clipped shadows and highlights that can be extracted from RAW. The latter ability is very rarely needed: I use it in less than 0.5% of shots, mostly to attempt salvaging shots that were accidentally badly under- or overexposed. And it won't do wonders. For all minimally decent shots, JPEG has all you need.
