[opencms-dev] Typo3 vs Open CMS vs ???

[jonathan soong]

[this is being cross-posted to opencms and typo3 lists]

Sorry if this has been asked 1000's of times before - i attempted to 
search the archives at:
     : Typo3, but they are not reachable 
(http://lists.netfielders.de/pipermail/typo3-english/).
     : OpenCMS - but these yielded few results (the few results said 
that Typo's image manipulation and news module were better)

In short, i am trying to compare OpenCMS and Typo3:
    0. *Are there any other _open source_ AND free contenders to OpenCMS 
and Typo3 at the moment?*
    1. *What features does OpenCMS have that Typo3 does not have?*
    2. *What features does Typo3 have that OpenCMS does not have?*
    3. *Why would you choose one over the other?*

Both seem mature and very active
I realise that OpenCMS is Java based and Typo3 is PHP based (this is not 
an issue for us, our IT department has mainly Java and PHP developers).
Features seem similar:
       - Image Manipulation - currenly Typo's seems better - is this 
correct?
       - Workflow - currently OpenCMS's seems better - is this correct?
       - Clustering/Load Balancing - OpenCMS say there's does it 
automatically - does Typo3 have anything like this?
       - Modules - it appears that Typo3 has many more modules avaiable 
then OpenCMS?
       - OpenCMS is XML based - does this mean it stores XML in the db 
or generates XML from the db? pros and cons?
       - Typo3 generates html straight from the db (?)  - pros and cons?

       - Both are extensible via modules - which is easier to develop for?
       - Both have user managment/permissions - which is better?
       - Both do 'project based publishing' - is either one better?
       - Both do caching - is either one better?
       - Both are WYSIWIG - is either one better?
       - Both have versioning - is either one better?
       - Templates are available in both - either one better?
       - Personalisation available in both - either one better?
      
Thanks for any feedback. If i get enough i'll cross post my findings :)

Cheers
