In addition to your points, if you intend to back up your ZFS datasets, it's easier with ZFS encryption to use ZFS commandline tools (zfs send) to ship the whole encrypted dataset over the wire. With LUKS you're shipping the unencrypted dataset instead. Arch has a good wiki page comparing LUKS vs ZFS native vs a few others: https://wiki.archlinux.org/title/Data-at-rest_encryption https://wiki.archlinux.org/title/Data-at-rest_encryption And more discussion of differences over at /r/zfs: https://www.reddit.com/r/zfs/search?q=zfs+luks&restrict_sr=on https://www.reddit.com/r/zfs/search?q=zfs+luks&restrict_sr=o...
