OpenZFS has worked fine for me, in mirror mode, for 15 years without anything resembling data loss.
When I had to replace HDDs, the ops were very smooth. I don't mess with ZFS all that often. I rely to the documentation. I must say that IMO the CLI is a breath of fresh air compared to the other options we had in the past (ext3/4FS, ReiserFS, XFS, etc.). Now BTRFS might be easier to work with, I can't tell.
btw, this bug is well known amongst openZFS users. There are quite a few posts about it.
