ReiserFS indeed has a bad reputation in that regard.
XFS' reputation is not entirely deserved, but not entirely undeserved
either. It assumes that there is a UPS, and that the filesystem will
always be unmounted cleanly. If that doesn't happen, then files of which
data and/or metadata was in flight when the system went down
unexpectedly will be zeroed, rather than corrupt. It would've been nice
if that had been a tunable parameter rather than an unmodifiable thing,
but other than that it's not an entirely unreasonable thing to do.
