I had to use WP professionally a lot of times, even though I didn't or don't like it.<p>Last year, I started using a Restful API WP plugin and find that Wordpress is actually really good. Specially because there's so many interesting plugins for it and I don't see any other CMS that have that amount of features available for free and specially being able to customize it quite easily and fast - by reading a few lines on the docs, etc.<p>I think that services like prismic.io are good, would solve my problems a few years ago, but now, Wordpress + Restful API Plugin + Angularjs and I'm done!
