FFS corrupted multiple times on me, with intel video driver freezing on OpenBSD. My short OpenBSD sidetrack ended after reliably corrupting itself the third time... every time video driver panicking, leaving a corrupted filesystem after reboot, when I had eg. ports install going on during panic.
Windows ran fine on the machine (Lenovo 200) before, and Linux ran fine after. FFS (and the intel video drivers) are the weakest part of OpenBSD in my experience, I liked many other aspects.

FFS will need a consistency check if it doesn't "unmount cleanly", but this isn't the same as the file system having been corrupted and losing data. If something really got corrupted and it was something else besides what you were writing in the moment the machine died, it sounds like a lot of data (for whatever reason large amounts of data was still buffered; usually an SSD is the reason) just hadn't persisted yet. With the exception of the old unadvisable softdeps feature, FFS doesn't defer a lot of writing. And It's possible to tell FFS to be fully synchronous, with the caveat that it becomes even slower than the sluggish performer it already is.
