Not convinced sorry
Highlights are recoverable with Jpeg
as well as raw
as long as there is still some "hidden detail"
If its "blown" its "blown"
whether raw or Jpeg you're still screwed
jpeg is technically described as a 'lossy' compression technique - that is to say, information is discarded as part of the compression process. By definition, a raw file will retain more information than a jpeg.
The other key difference is the jpeg image has already been processed by your camera; thus if you have any picture style setting, or in camera sharpening enabled, this will have been applied to the image before it is saved, and this can not be reversed. You can of course turn these settings off in the whole, but some, white balance for example, can not. So again, a raw file will have more 'virgin' information in the file, where as the jpeg will have processes information.
Finally, repeatedly editing a jpeg file and saving it will compound the information loss and can degrade the image. The same is not true of raw.
On the other hand, raw files are much larger, and do require a degree of PP just to get a decent result. Sometimes, it's just not worth the additional space or effort as jpegs are pretty good now-a-days...
Personally, I use both formats from time to time, depending upon what I'm shooting and what I want to do with the images. I've set up my main camera to write RAW to the CF card and jpeg to the SD card as default, so best of both worlds.
