No personal experience, but someone recently pointed out this article
to me:

"Btrfs considered … helpful"

Yes. It ran great for over a month but once we had some serious data in
it (multiple terrabytes) it died, more than once, and the last time was
so bad it was unrecoverable. This was just this summer and yes we were
using the latest.

We have found the ZFS on Linux is working quite nicely.

I do have a development machine using constrained SSD disk, and I would
like to take advantage of compression.

But would not want to reformat everything on ZFS (I'm actually using Ext4).
Nevertheless, seems that Joe had a bad experience with Btrfs (my
expectation was to just migrate from Ext4 to Btfrs and be able to take
advantage of a brand new FS features).

Thanks, I'll play a little with both (using VM) and check if there is
anything simpler.
