I very much like how Guix is just a Guile Scheme library and can itself be integrated with other Scheme code. There is, for example, guix-web, a web interface to the package manager; there also is an Emacs interface using geiser.

Using Guile has turned out to be a great feature in itself and it is still fueling the development of new features that otherwise would be awkward to implement, such as the new "guix graph" command to visualise dependencies.
