Doubt in NAND and NOR gate.

Question

Why NAND gate is preferred over NOR gate?

Answer 1

1. NAND gate can be built with fewer transistors than a NOR gate.
2. AND gate's output is only HIGH when both inputs are LOW, making it less sensitive to small changes in the input voltage. AND is used to build NAND.
3. Low power consumption then NOR.
4. Fast processing then NOR as few transistors used.
5. Highly available 

Comments

I think NAND gate output is high when at least one of the input is low.
