Wulf,
I played with both the raw and the jpeg versions and was able to get very similar results on both sides. I should say that I always shoot in RAW, just because I can, and as others have noted, storage is cheap. I just had dinner last night with a very successful photographer friend who does major live theater, almost exclusively, and he shoots a 5DmkII almost all jpeg, for speed and file size, unless a client explicitly requests RAW files. His opinion on the matter is similar to yours.
Here is my "final" version from the RAW processing.
Here is my screen grab from photoshop.
Both are available full size on flickr.
