I think the only big thing you missed was GOOPS's level of
customizability, which one you to create virtual slots, automatically
define slots for classes of a particular metaclass, and such like.

It's good to have another option than GOOPS. I imagine the major
reason someone might choose to use SOS instead of GOOPS would be the
C-level access.  (And I hope we can one day work out something like
that for GOOPS!)
