Or your jpgs, of course, although if you have a sky as in my original image, there will be no detail left in your jpg.
The discussion raw vs jpg has been beaten to death. Many times over.
“Jpgs look a lot better when they come out of camera!” Of course they do. They are processes IN-camera with either the default settings from when you bought the camera, or the customized settings that you entered. Raw images always look flat and boring when they come out of the camera, because you’re looking at unprocessed data. YOU need to do the post processing, and here’s the good thing: you get to control what’s happening 😉
In any case, fact is: raw files contain more data to recover than jpgs, so if you have the time to fuss around in post-processing, then do shoot in raw. If your end-goal doesn’t require high resolution and/or high detailed material, and you don’t have too much time on your hands to spend post-processing, you’re better off shooting jpg. Or if you have money to burn on memory cards, shoot both, so you can have the goodies of both worlds.

D700, ISO200, 1/125 sec @ f/8, Nikkor 50mm

The above is the originals. Yes, IS the originals, it’s only one file. It’s a fake HDR, basically. The left image is the original exposure @ 1/125 sec. The right one is the one where I pulled down the exposure slider in Lightroom almost all the way to zero. That gave me just enough detail in the sky to work with (try that with a jpg! 😉 ).

I opened both instances in Photoshop and copied the right one onto a new layer.

First two adjustment layers are to make the sky blue. The rest is for bringing out the colors in the walls and roof of the buildings. The last -curves- adjustment layer is for the street. The top layer was added to straighten the buildings.
