ZFS is incredibly easy to learn to use, whereas btrfs is quite complicated to learn/use, and even more so if you've used ZFS since a lot of things are either just different enough to be weird, or so different that it makes no sense. Examples: ZFS snapshots can be recursive (-r) or not, whereas on btrfs they cannot be recursive; in discussions I've seen, this is mentioned as "a feature", since you can create a subvolume for data that you don't want to be part of the snapshot, but it also prevents you from dividing up a logical heirarchy into multiple behaviours (compression vs. not, block size, etc.). |

Bind mounts can get around most of the limitations here, at the cost of polluting one directory with the canonical locations of all your special-purpose subvolumes. I think it's still awkward to simultaneously snapshot every subvolume that is mounted under a particular tree for incremental backup purposes.
