I've been overall very happy with: - Arch on BTRFS RAID1 root, across 3 dissimilar NVME drives (about 7 years, 3 drive replacements for hardware failure, I don't think ZFS supports this configuration) - numerous low-power systems (like Pi3s) on BTRFS root (also going on 7 years for several of these, lighter on resources than ZFS) - Asahi NixOS on BTRFS root (kernel doesn't support ZFS) My NAS and several larger datasets are on ZFS based on reputation alone, but honestly I've had more data loss scares with ZFS than BTRFS (drives that have disappeared for no reason then reappeared hours later, soft locked and unable to unmount indefinitely, several unfortunate user-error issues with automounting datasets overlaying necessary top-level directories and preventing successful boots), and I find the BTRFS tooling more intuitive. For my hobbyist-level homelab type needs, I would say I'm overall pretty happy with BTRFS. The only issue I've never been able to resolve is regarding lockups when issuing quotas -- another reason I stick to ZFS for my spinning rust storage drives. Oh, and the ZFS ability to mount a zvol as a foreign filesystem (words?) lets me `btrfs send` backups to ZFS, which is nice!
