Another anecdote - on working Xeon E3 hardware (so ECC, etc) I have had btrfs corrupt itself as recently as 5.x kernels from just normal use with compression on a single root device. ext4, xfs and zfs work flawlessly on the same hardware. Furthermore - btrfs feels excessively complicated for simple workflows - if I want to snapshot a btrfs volume without exposing the snapshot to the machine’s view of the file system, I have to do a bunch of volume layout setup first. With ZFS I can just snapshot.
