Should I use WordPress or Joomla?


I want to rebuild a website and move its content onto a CMS. Site is currently hand-coded.

I know Joomla is more sophisticated and I think WordPress is simpler to use. But I don't know which one is the best for me.

The goal is to develop, extend the site (which is a blog-like site) and add more complex features to it, to modify the design/layout/template and I also need the best security (against hacking).

So: should I choose Joomla or WordPress? And why?

Thank you in advance! :D
