@InternetPirate I've been happy with Ubuntu since 2007, I don't always like Canonical's choices, but they're easily changed. Recently tried Vanilla OS, easy install and seems solid, good alternative to Nix I think.
From what I understand from this page and other sources - you have to type that to run gimp or other app. At least that's the impression I'm getting from the documentation. I run most of my stuff from the console and don't like to use aliases.
