Based on following parameters we can say IS-95 system is best

1. Multiple access technique CDMA, TDMA (Used in Both GSM & IS-136)

2. Modulation BPSK with quadrature spreading (π/4 DQPSK in IS-136)

3. Carrier separation 1025MHz (30KHz. In IS-136, & 45MHz in GSM)

4. Voice channels per carrier 64 (3 in IS-136 & 8 in GSM)
