Usually in my experience whenever someone has a problem with zfs it’s solvable in one way or another and the devs are very responsive on irc and GitHub. On the other hand a lot of problems caused by btrfs is unrecoverable and a mess. Ext4 is stable but lacks the feature set that makes customers go to zfs instead (and that is fine, software should do one thing well and right).
