If you find WordPress too complicated, you can stop right here. The Joomla! CMS definitely has some nifty features built right in, most importantly, management for multilingual web pages – but it’s complicated! While WordPress sometimes almost feels like a website builder for beginners, you’ll find Joomla! much more complex. Just look at the screenshots below.
I agree with you that Pulse CMS offers an interesting way to go, without databases. Before moving all my sites to WP over the past two years, I had always felt reluctant to use databases: but testing WP had convinced me to go ahead. Although I do not use it at this point (I played a little bit with previous versions), I bought a Pulse CMS license, if only in order to support that interesting project. I do not rule out using it for a site some day, at least experimentally.
