The jpg engine in-camera is SUBSTANTIALLY better these days than what was in the 1d4, 5d2, etc. In fact if you tweak enough of your settings, you will be hard pressed to get much better results shooting raw vs jpg. I have spent a season of NBA to come to this conclusion. The only time that you might significantly do better with raw is during high DR shooting.
I agree - I do shoot raw + jpg but rarely touch the raw and im almost at the point It will be jpg only as the IQ is way above what we use to get .
My 5Dsr jpeg files are as good as I could wish for and My 1dxmkII is just the same as long as I get the exposure about right and i check that quite a lot while out birding .
Yes Raw may save the day if you screw up but Don't screw up
