For lossless codecs, the only difference is the amount of compression they give and the speed at which they compress. Lossless means just that, there is no loss, no changing of bits (other than where errors on the disc are found from scratches, etc).

So as long as you retain software that will burn from your chosen lossless codec to CD, it doesnt matter which lossless codec you use.

The biggest question when ripping with a lossless codec is will your music player (iPod, Rio, whatever) play back your chosen codec.

While disks are relatively cheap, it doesn't make much sense to me to store songs in raw format as there really is no need with the lossless codecs.

You gain nothing and lose diskspace by keeping songs in raw audio format.
