The best free open source CMS (content management system) solution?

content-management-system

I want to convert a website to use a Content Management System for updating a large number of content pages for a website. The current website is mostly ASP.NET, but I am considering converting to PHP if it means I will have better integration with the "CMS of choice" in the market. I have heard of Joomla! and other CMS' but I would like some answers to which ones are considered better. Features that I need to support are custom sidebar and tab menus (with expandable javascript drop downs for example). Can anyone tell me of a good solution?

Best Solution

You should look at opensourcecms.com. It's a site that hosts demos for the majority of open source CMS's out there in both PHP and ASP.NET. You can try each one out and read the features and reviews. It's a good way to find one that meets your needs without actually installing them.
