A very quick Summary: www.threeeyedbird.com/blog/2016/10/21/why-modx-is-our-cms-of-choice-and-not-wordpress-(gasp!)/

WordPress was built as blogging tool. MODX was built as a pure CMS.

Wordpress is less expensive to get started, and has a larger selection of templates to choose from.  In a few special cases it is easier to integrate with outside content providers.  For example Real Estate Agents should use WordPress for easy integration with the MLS.

ModX gets hacked much less often than the other CMS's.
