I spent around 3 years working with Drupal 7 and and about a half a year with Drupal 8. For D7: * The frontend and backend are too tightly coupled. * The views system was awful to design custom, complex queries for. Documentation was scarce * No dependency management * Lots of weird hacks to do standard things, like the Features module * The hooks system can result in a lot of complex, unclear logic I've since moved onto the python/js ecosystem and it's much easier to build sites in
