Joomla is a Content Management System. The initial installation comes with a complete set of articles and menus to show what's possible. You can easily change or delete the articles you don't need. I find it ok that Joomla promotes itself on its default installation. Once you get the hang of it you can do nearly everything with it. Don't give up so easy.

But of course, if you like Wordpress better go with it. It is your website, your design. Use what you like best. It's all about fun and feeling good about it in the end.
