I use it everywhere, raidz2 on HDDs for a NAS also with mirrored NVMe root pool, and on a couple of laptops. zfsbootmenu is awesome, so I can boot into any snapshot, and a pacman hook that creates a snapshot whenever I upgrade packages. Even if it’s overkill for some of my use, I use it anyway and trust it much more than anything else - it has a proven track record. Backups to sync.net are a breeze with borg/borgmatic.
