WP is the best choice. It's fast, robust, backed by huge community, better than ever before and that's why it's so popular. You get a range of plugins to play with and make your website truly yours with custom themes.
Ghost is a minimal content-focused blogging platform. It's fast and secure. Both WP and Ghost are easy to set up. You can also use Jekyll if you are planning for extreme minimal blogging and nothing else.
Joomla is a CMS who's major concern is with the e-commerce based dynamic websites. Joomla and Drupal can be categorized in the same category relative to Wordpress.
Though I haven't used them, but there's an odd feeling with these names, Drupal and Joomla, so I prefer sticking to Wordpress.
