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.
What does snowflakeOS do differently than nix ?
Is it perhaps like endavourOS and Arch linux ?
It is the endavourOS of NixOS.
However, making NixOS more user friendly is a lot more work than simply offering a default config. Most of the work/challenge lies in the GUI NixOS configuration editor.
Maybe it's the soulless cynic in me speaking; but the obvious snow-theme around NixOS notwithstanding, 'snowflake' MIGHT NOT be the best name for a distro aimed at 'casual users'. It's as though they're saying, 'LOL! You snowflakes can't be assed to figure out how to install nixos, but still want to reap its benefits? We got you precious snowflakes LOLOLOL'
