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 haven't yet run into any piece of software that's fundamentally incompatible with the immutable model thanks to distrobox. This also means I don't have any packages layered, so updates are very quick.
