I'm a big fan of RAW - it's the digital equivalent of film! Makes it so easy to fix white-balance, etc and saves a lot of "fiddling" time when shooting. Getting it wrong in jpeg can mean what would have been a very nice photo gets sent to the trash. Also, RAW handles saturated colour much better (jpeg tends to fall apart in a screaming heap when red hits 255).
RAW doesn't have to be time consuming post-processing. I "tune" one image in a given set (same shooting/lighting conditions), then "past recipe" to all the other images. The other thing is you don't need to fix up every image. Only focus on the ones you really like (check-marks are great for filtering). If your shooting settings are close enough, you can often get away without any tweaking.
As always, practice makes perfect
