Linux Mint Debian Edition. I mention it a lot on here, but it really is my favorite distro. I have been using Linux a long time, and I'm old. I don't care to spend a lot of time and effort tweaking and configuring. LMDE gives me everything I need and is usable out of the box, while not standing in my way when I need to get shit done.
I just distro hopped to nixos. I was unaware of it until I came to the fediverse. The declarative system, once you get over the small learning curve, I feel is very easy to understand and configure. Creating and being able to roll back system configurations is a great feature too.
Previously I was using void. I quite enjoy it too and am sure I'll revisit it. It's a light (no systemd) rolling release distro with an emphasis on stable packages.
