Because, CMOS propagates both logic o and 1, whereas NMOS propagates only logic 1 that is VDD. The O/P after passing through one, the NMOS gate would be VDD-Vt. Therefore, CMOS technology is preferred. In CMOS logic gates, a set of n-type MOSFETs is positioned in a pull-down network between the low-voltage power supply rail and the output.
