CDMA and GSM are two different technologies and choosing
best is not possible because both have advantages and
disadvantages. Like there is no limit how much customers
can be connected at a time in GSM but more number of users
quality will degrade.
In CDMA only fix nos. of customer can be connected at a
time. And that's why quality will always be good.
Handshaking is easy in GSM so less call drop when changing
the cell.
In CDMA handshaking is difficult so there is more chances
of call drop.
