That depends on what you want a command-line parser to do.  As I've
mentioned before, our software has very complex option specifications
(nested options, etc.) that really require a formalized parsing
structure to make any sense of it.  Spirit is perfect for our needs.
Any command-line parser that doesn't allow extension to such
option formats is essentially useless to us.

Using a formalized framework should make it easier for Boost users
to extend the command-line parser, especially given Spirit's
ability to support dynamic parsers entirely within the C++ language.

Assignment to program variables can be trivial.  Again, it depends
on what you want to do.  Validation is always hard.  :)
