Not Brazzite, “Bazzite.” It’s a mineral, and its naming proximity to an adult website is entirely coincidental (and I would hazard a guess that the mineral was named first).
Honestly, I’m not that concerned with Bazzite being newer, because it’s based on Fedora CoreOS. It utilizes rpm-ostree to manage system upgrades, so for any bad updates, you just rollback to any previous deployments (and you can pin specific ones so you are guaranteed a stable rollback point). Additionally, you can rebase at any time, so you can swap out the system layer for another ostree-based image without touching any of your files in /etc, /var, and /home.
Pop!_OS is a great choice, too, but the biggest problem facing the family of Universal Blue distros isn’t notoriety, it’s the fact that Fedora Atomics in general are still relatively new. The examples are still being written, and people are getting used to new tooling.
But if you don’t need specific customizations like me, and all your software can be found as appimages or flatpaks (or is already installed), Aurora, Bluefin, and Bazzite are all rock-solid choices that will “just work.”
