Wordpress is old, and they've built up a shit-ton of technical debt for the sake of BC. To put it bluntly, it's not a pleasure to work with, at all. On the up side, something like 20% of the surface net runs on Wordpress. There's a huge market for WP skills, and it's got enormous mindshare amongst non-technical types. If you want to invest effort in WP, do it because of the adoption metrics; if you're more technically oriented, pick Django (or Laravel/Symfony if PHP is more your speed).

Actually there are some great cms built on top of django, for example django-cms or wagtail!

If you start from scratch and want to build a simple cms it will be easier to do it with wp, if ofcourse you tolerate php - some people won't use php for reasons that should be well known to hn readers. However, for any other web development I recommed using django (or another normal web framework).

Using wp to build non-cms stuff reminds me the "when your only tool is a hammer everything looks like a nail" argument! You may use your hammer to cut (break) wood but using your saw would be easier and safer!

What?

Django website have "The Web framework for perfectionists with deadlines".

You can compare WP with Drupal or Joomla. With Django you can build you own CMS.
