For me it’s PeppermintOS.
I started my Linux adventure a few years ago, and haven’t owned a Windows PC since.
I currently use Arch on my main rig, and I wanted to install Linux on two old laptops that I found laying around in my house
I then remembered the first distro I ever used, which is PeppermintOS, and I was amazed at the latest updates they released.
They even have a mini ISO now to do a net-install with no bloat, with a Debian or Devuan base.
Sadly, I believe the founder passed away a few years ago, which is why I was really happy to see the continuation of this amazing project.
Intuitively, without doing a detailed comparison, I agree that Guix and lisp would make things easier.
Network effects so far has been my reason for not trying Guix sooner along with the free software only… though free software only has also simulatenously pushed me towards it :)
Distrobox, is something, I don’t think I’d be too interested in. However I’m probably just annoyed at being forced to use unreproducible docker images all the time and biased against containers because of it.
I’ll have to give it a try!
