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

Thanks. Too bad you didn't find Drupal worth hanging around for. Great you found a stack that makes you happier.
