When I raw process a photo on my Windows desktop (photo from from my Nikon D5200) and compare it to the JPEG offered up, it always has a very slightly different perspective ... not the correct word but it's the only way I can think to describe it. My point is that if I wish to do a composite with the JPEG it doesn't work because things are in different places and even edges will be cut off on the raw processed photo. It almost seems that the raw processed photo, because of this, is often even less crisp looking. I'm not sure what happens there. I would share an example but the difference is slight so it won't be real obvious unless you're trying to create a composite. If requested I will find an example.
