I just really like portage, I guess. I know how to use it, and learning how to do the same thing in guix doesn’t offer any benefits that I know of that matter to me, yet. Maybe one day.

I use Gentoo, and atomic just doesn’t seem like a fit for me. That said I could see it being great for people who don’t tinker. If I were to get a family member to use linux I might pick an atomic distro.
