Are you not surprised that GSM sounds better than CDMA?

No. Quality depends on a variety of factors including both the codec and (bandwidth efficiency vs number of users). Qualcomms major gain is in bandwidth efficiency and codec quality (they use a later, more sophisticated codec than GSM - although there is a new one coming into use for GSM), but if the CDMA systems are more heavily loaded relative to their ultimate capacity, then they might indeed show lesser performance.

However, I would be surprised if CDMA didn't allow considerably more users per unit of bandwidth, cell size and voice quality.

PS A codec is the device that takes your digital voice and removes the redundant bits (hey - I've spent too much time in the old British Empire.) or adds them back in at the other end.
