В чём zfs удобнее, чем btrfs: http://rudd-o.com/linux-and-free-software/ways-in-which-zfs-is-better-than-btrfs

These are all things you might want to do, but you'd have to ponder whether it is worth doing given the added effort to do them. ZFS makes it effortless to use these features, without adding any additional work for you. Thus, ZFS makes it possible to do what you want, whereas before with btrfs you would have said "naaah, that's too much work for very little benefit". In this sense, ZFS offers advantages that make btrfs look as cumbersome as LVM in some scenarios.
