The point of ZFS is to prevent layer problems by making one
entity responsible for most of them; so, if you were already
going to use several of:

- CoW
- RAID 
- integrity assurance
- snapshotting
- multiple filesystems sharing a storage pool
- automatic spares
- compression
- deduplication

or the other features that ZFS supports, then ZFS makes sense.

If you only want one or two of those features, it's less obviously a good
choice.
