I've heard good things about Arch. Indeed, I installed it on one of my boxes, where I specifically wanted to avoid a lot of compilations, besides being curious about it.
Used it for a bit over a year know and... I don't know, it hasn't been as stable, and I've find using AUR more of a chore than custom ebuild repos. It's probably great when you get used to it, but so far I still prefer Gentoo.
It's great, that there are several good distros for different use cases, and that we have the freedom to choose what suits us best!
Syncing over iCloud drive works well (Obsidian, iOS).
