With Guix you have reproducibility, freedom, good docs and peace of mind, also when configuring things more deeply. You also have a powerful programming language (Scheme / Lisp) with which to define your system config as well as your dotfiles. This is my insight after years of GNU/Linux usage. I run Guix on laptops, desktops and servers, and I never have configuration drift, as well as the benefit that I have a self documenting system.
