The problem is that when you shoot jpeg, you are allowing the camera to make certain decisions for you about the coloring and lighting of the photo. Sometimes the camera makes good decisions, sometimes it makes so-so decisions, sometimes it makes downright awful decisions. By shooting raw and making those decisions yourself, you get a better photo.

I shoot both raw & jpg. For many candid shots, the jpg is just fine. But sometimes the lighting is complicated and the camera screws up the flesh tones, especially if any fluorescent lighting is involved. Then I pull up the raw image and adjust the white balance manually. Or, the jpg version might have some shadows or blown out areas. If I work with the raw, sometimes I can recover detail in those areas.

So yes, the camera is good enough to capture the data off the sensors, but once it has that data, it doesn't always make the best choices in converting that data into the most pleasing photo. The human eye can make better choices in post processing.

Ideally, the goal is to spend more time shooting and less time in post processing, and that's where getting the best quality camera comes in handy.

I stopped using RAW over a year ago now. The main reason being that the file sizes are too large (15mb) and take much longer to process.
The Jpegs produce very high quality images and are quicker to process if required.
I give my photos two tests:
1:Zoom into full screen (Equates to A2 paper size)
2:100% crop.
These check for sharpness and colour etc.
If test no 1 is satisfactory I would almost certainly keep it.
This test is more critical but if I am happy with the image quality it will confirm my first choice

Boy! Talk about a discussion that has totally drifted away from your question! I shoot both jpeg and raw with both ff and crop. No noticeable difference. The FF has higher resolution and therefore both jpegs and raw should be more true.
I don't think anyone here sees jpeg and raw shooting as mutually exclusive. As long as you have the storage media for raw files, it's a good idea to take them and also take jpegs. If you want to play with your photos in PP, then your raw files will offer much more flexibility, since your jpegs have already had some PP decisions made for you in camera.
