Recommendation? Best CMS software for someone familiar with DreamWeaver?

[Jem]

Wondering if anyone here who worked primarily with DreamWeaver in past years has found a Content Management System (CMS) that is easy to setup and use, and that plays well with DreamWeaver?

Or does what comes in most CMS packages obviate the need for DW?

I have recently had inquiries about helping set up some CMS based sites, but alas my background is mostly in DW (and the underlying HTML, etc.)

Are there any that are a natural "fit" for those with DW experience? I've looked briefly at Drupal, WordPress, Mambo and Joomla, but want to make sure I'm not missing something obvious before diving in deeper.

Thanks.
