I've used F2FS before and ran into similar problems mentioned. My partition became unusable and fsck.f2fs didn't help. I lost the files, but thankfully had backups.

Since then, I have found that exFAT was better suited to my use case.

This was a few years ago now, I came away from the experience thinking the ideas are nice but it needs more time to mature.

Obviously this is all anecdotal, I've lost partitions to plenty of filesystems before, but the fact that little to no data recovery software existed for F2FS at the time was really the concerning factor.
