XFS a good contender. On SGIs.

The file-destruction problem certainly still exists:
It can make some types of debugging very painful. For example about a month ago my Xubuntu dapper system (using XFS) was having trouble getting X running on multiple video cards, and the failure mode of X was a hard-lock of the machine requiring a power-cycle. The use of XFS pretty much guaranteed that after reboot, Xorg.0.log was useless for debugging the problem. In at least one case it also null-filled the xorg.conf file that I was using for testing. I quickly got in the habit of typing "sync" a few times before doing anything even remotely risky, in hopes of protecting at least files that I wasn't actively working on.
I don't know what's worse -- the fact that it fills the file with null bytes, or the fact that it leaves the metadata intact so that the file looks fine if you just do an "ls". A similar experience with Reiser4 resulted in xorg.conf disappearing entirely after a hard reboot, and perhaps that was a better way to fail since it was at least obvious that there was a problem.
That said, I'm still using XFS.
