Depends on what you're using it for.  We've had excellent luck with iLBC 
for voice quality and g729 as well. Speex is better than GSM, but not 
spectacularly.

The problem with all of them of course, is transcoding. They have less 
of a bandwidth footprint for acceptable quality, but more of a processor 
footprint.
