To me, zfs is like the Gentoo of file systems. If you actually use the zfs features and do a lot of digging and experimentation before you go all in on it, it’s not bad; it really can be quite good. If someone wants a filesystem that they format and forget, ext4 and xfs are still solid options. I used to use ext4 for most of my filesystem needs and xfs for my long term storage on top of mdadm. I just really wanted zfs snapshots.

Zfs is great if you need a raid with parity: their raid5 and raid6 are the best in class. I have a NAS build where it makes sense to use those.
If you only need snapshots, go with btrfs. Just stay away from their raid5 and raid6, because they are unstable and tend to lose data.
