I recently switched from arch to kionite and I quite like it a lot. There is defenitly more stability and security. Although rpm-ostree I quite a learning curve compared to pacman.
Either way for anyone curious ask NY anything about the distro / the switch to it.
I tried bazzite, which is very close to kinoite, as Fedora itself had a great out of box experience, even on laptops.
Whilst there was a way to get most setups, apps and configs working it was clear I would eventually run into a piece of software that the effort to get it working was not worth it. Some software and development tools are not (yet) designed and maintained to easily work in an immutable environment.
My biggest gripe was that any interaction with os-tree meant that updates now started to take a really long time building the image with high CPU/power usage. I wasn’t ditching Windows to go back to a world of unnecessarily long updates.
For some, I can see the immutable can work well if they want an Android like experience and can accept the software catalog available. It wasn’t the right model for me, as I expected my machine to do more than point and click app install. I would be curious how your typical arch user would find it.
