Neither.

If your channels use gsm|ulaw|g729|whatever, encode your sound files 
(prompts, music on hold, everything) in that format.

If you have your sound files encoded with the same codec as the codec your 
channels are using, Asterisk does not need to transcode so the "cost" is 
minimized.

The "workflow" is to rip the cd to disk and then encode to the desired 
encodings.

cdparanoia is a great ripper. cdda2wav is also common.

sox is probably the most commonly used tool for encoding.
