We can save the power if we are using CMOS 
That is power concemption is low.

CMOS is preffered because we can reduce the complexity of the circuit and also much power is saved

What about Manufacturing problems faced by CMOS over NMOS? Manufacturing CMOS is difficult when compared to NMOS and PMOS because CMOS includes both NMOS and PMOS. Whereas NMOS and PMOS has uniform structure and hence easy to manufacture.

CMOS is preffered over NMOS

as CMOS propogates both logic '1', and '0', without a voltage drop

when using NMOS only, logic '1' (i.e Vdd) suffers a thresold drop and the output after passing through one NMOS gate would be Vdd-Vt(thresold voltage of the NMOS gate).

Hence signal margin is very important in NMOS causing possible SI(signal integrity) issues.

Hence CMOS is preferred. By the way CMOS and NMOS and also PMOS are all low powered. Static power consumption is the same, dynamic power consumption depends on signal swing (i.e number of times data line varies)

The most important advantage of CMOS is the very low static power consumption in compare with NMOS technology.

CMOS provides more noise margin than NMOS.
