How did the aztec society differ from the inca society?

They had different religions, beliefs, ideals, lived in different regions, and etc. Their culture as a whole are different even though certain aspects are similar.  

The differences between the Aztec and Inca societies were:
-Inca's empire was more vast than the Aztec
-The Aztec methods of communication were less advanced
-Different locations (Inca - Andes Mountains, Aztec - Mexico Valley)
-Different forms of documentation
-The Aztec were industrialized whilst the Inca relied on agriculture
