I use Fedora Kinoite daily and find it to be the only OS to make sense really.
I find Fedora CoreOS totally confusing (with that ignition file, no anaconda, no user password by default, like how would I set this up anywhere I dont have filesystem access to?)
But there are alternatives. I would like to build my own hardened Fedora server image that can be deployed anywhere (i.e. any PC to turn into a secure and easy out-of-the-box server).
As modern server often uses containers anyways, I think an atomic server only makes sense, as damn Debian is just a pain to use.
Because containers (Distrobox, Flatpak, etc.) are bae.
You can read my post I made a while ago for more information: https://feddit.de/post/8234416
Once you "get" image based distros, you probably never want to go back. Traditional distros just feel... off now for me.
Containerisation is the biggest strength in Linux, we use it all the time on servers, so why not on the desktop?
Atomic OSs just make more sense for me, not only because of security/ bug/ whatever reasons, no, also because they feel simpler and are pretty convenient and robust.
