I run Guix System on my personal laptop and Project Bluefin on my work machine.
Guix is even easier to get started with now thanks to the Guix Packager , a web UI for writing Guix package definitions.
Project Bluefin auto-updates thanks to its use of container images deliver system updates. It’s also just a great platform to get started writing containerized apps, since it ships with rootless Podman by default and you can easily add new developer tools using just commands.
