Adobe Experience Manager can be mentioned as an inferior product tech stack wise, but strong marketing including targeting the C level with PowerPoint presentations let’s it win customers.
Feature wise Wordpress needs to do something at the analytics level. It does not make sense to host everything via Wordpress however everything data related is done via third party analytics. This is also Adobe’s selling proposition (marketing cloud) and they have a point here, however weak, since for example Adobe Target is some very basic “if then” rule system. But it might impresses C level noobs. ;)
