[TYPO3-english] Typo 3 vs Composr CMS vs MODX CMS

[Keith Miller]

I am looking for a product that offers document management (gallery and download files), and forum features. I have collections of audio and video files and intend to sell through the site.

Though I like MODX, I am preferred to pick Composr as it offers in-built PayPal subscription. That saves me some time with coding.

However, I came across Typo 3.  I wish to know how Typo 3 will meet requirement when compared with the other two products mention here. How do they perform when compared with Typo 3?
