I've been managing a Btrfs mirror with snapshots on my workstation for the better part of a decade.
I really want it to be as good as OpenZFS, mostly so I can write a administration guide like I did with ZFS. But it's not there—not by a long shot.
This is a damning article (2019) about the shortcomings of Btrfs, yet resonates with my personal experiences almost exactly.

@atoponce So much agree. ZFS worked better for me but I don’t want to manage an out of tree kernel module.
So it’s back to boring old md/lvm for me.
It doesn’t have all the features, but it does what it does.
And `df -h` doesn’t output nonsense.
