Linux

I have had corrupt filesystem errors with BTRFS on both of my computers due to power outages and one hard shutdown (had to)

When did this happen? what error did you get?

Btrfs will explicitly go read only when it detects corruption, which is a good thing, with EXT4 you don't know what is going on until it is too late.

fwiw the only time I managed to get info from an user that had "issues" with btrfs, I discovered that what had happened is that they moved the partition that had snapshots, and if you don't know it, this is catastrophic because this unlinks all the snapshots and suddenly everything would take many times more storage.

Used ext4 for YEARS (I am old) and never had these issues with such frequency

The short time I've used EXT4 running into bad superblock errors was something that happened almost every week, but in the end I was always able to repair the disk and recover everything.

I'm from Venezuela, power failures are common here.
