I’m also on Bluefin for my daily driver and Bazzite for my Steam Deck. I love it because the important part is set and forget it, and the part I tinker with is separate from the part that keeps things running. And if an update borks something, you can just revert to the image you came from.
If you haven’t already, take a look at Bazzite for your desktop. I’ve actually replaced SteamOS with it.
