Despite all its feather-flashing, the Ruby community is yet to develop a killer script, or even a renowned forum or blog script, let alone a top-of-the-class CMS.
If platform and language weren't a problem I'd always back .NET over any other language. Python and Django in particular has some fantastic scripts, but its enterprise offerings and Umbraco in the open-source world makes .NET just far more proven to handle websites and be good to develop on.
