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.
I love the idea of peppermint OS but it didn’t work properly on my laptop both times I tried it, first time it wouldn’t install any of the extras I selected during the install process and the second time using the Debian 12 base it just straight up wouldn’t give me an option to install extras and the window would instantly close when I tried to open it. I really love the ideology behind it and it is a speedy OS but I’ve ended up going to LMDE instead while I toy with the idea of Arch.
