I'd probably use arch if there was an easy general immutable/atomic version of it. I just don't trust bleeding edge rolling enough to not have that kind of a safegaurd.
It's a pain. Stuff does break for no reason. I'm a slave to it's enhanced hardware compatibility and higher success rate at running proton games that are borderline. You just can't beat the wiki and the community support. It's too good to not have. But you still run into issues it's just that I'd be no better off on a different distro.
Grub has many features & addons that many others are still lacking though. But maybe we'll see some improvements in that area now as well. Still sucks for an end user.
