Taracor is half right IMO, and really this topic is all about opinions and not right / wrong.
I always used to shoot in Normal JPEG quality. I could not tell the difference between fine JPEG or RAW. However... I now shoot exclusively in RAW. The reason being is that I can fit less images on the card. In JPEG I found myself going out and taking 400 mediocre images and having to sort through them afterwards. Since switching to RAW I often look at a scene in great detail before pressing the shutter, and when I realise that nothing good will come of it I leave it rather than adding another 30 seconds of reviewing and deleting time to my post processing.
The other benefit is if you ever need to adjust white balance, exposure, colout etc the quality difference between RAW and JPEG becomes very clearly noticable. Ken Rockwell like many photographers seems to just like taking pictures and has no concern of getting the highest quality out of them.
My suggestion is shoot in RAW and review the photos as soon as you get home. If they all look great which may be the case, just batch convert them all to JPEG and delete the RAWs. It offers you much higher flexibility and error lattitude.
