The analog calls require several times the bandwidth of a digital call. The voice quality was slightly better but at a great expense.
With digital calls, sampling is not the issue. The compression of the speech sometimes causes artifacts to appear.
Also, loss of packets on the radio link also hurts the voice quality.
The voice coders are getting better with time but you will never get toll quality voice on cell phones.
