In a two phase three wire system it has a neutral current which is greater than the phase currents while in 3 phase 4 wire transmision neutral current is almost zero in normal condition.

Motors running on three phase tend to run smoother than those on two phase.

2ph causes more current lag and less torque. also we have to use capacitor or other things to make 2ph system rotating. while 3 ph does not need any such arrangement.

2 Phase motors have low efficiency and low power factor. There are higher chances of stalling.

MOST IMPORTANT: 2 phase load will create imbalance in the power system and high current and bulky too. Why should we use it when we have more efficient 3 phase induction motors

Two phase motor essentially use in domestic use like water pump set ... It gives high torque and low efficiency. The phase diff 180 or 90 make the two phases with the help of capacitor.
