Migrating from NixOS to Guix experiences/tips requested

In light of the recent sponsorship policy and potential NixOS foundation conflicts of interest no one has publicly denied, I’m currently evaluating moving to guix or at least having it as a backup plan.

Has anyone done this that can share their experiences or tips in doing so?

Feel free to remove this post if deemed not appropriate, but know that I personally won’t see it as a very healthy indicator of NixOS and I’m sure many others feel the same.
