At my job one of the sites I work on, a large government agency you have heard of, uses Drupal. And honestly? I like Drupal more than Wordpress as a developer.

But, I will say, Drupal is definitely confusing at first with all its nodes and entities and content types and poor documentation and so on. But on the other hand, it doesn't really force you into anything. You can build almost anything with Drupal, which I think makes it a great CMS.
