Anecdotal, but I had a power outage at work last year and my relatively freshly-installed 18.04 system, for which I chose btrfs as the root filesystem, completely corrupted. I managed to extract most of my data to another disk on another system, but it was pretty shocking. I haven't seen unfixable filesystem corruption like that since ext2 in 2001. I'd completely forgotten it was a thing, but there I was in 2019 trying to use a second linux box to salvage my data. Of course, whenever I mention this the btrfs zealots always come out of the woodwork saying "you must not know what you're doing if you broke btrfs" or "you obviously didn't really try if you couldn't get it fixed" or a half-dozen other excuses, but in the end I've just completely given up on btrfs. It's just not worth the hassle.
