I would say ufs2 easily wins, but remember this is the freebsd-questions
list ;) There are some differences though, ufs2 uses softupdates, not
journaling(journaling is available and easy to implement via gjournal).
Softupdates I believe are a little faster than journaling, but it's drawback
is long disk checking after a dirty shutdown. I've never had a ufs specific
issue in hundreds if not thousands of deployments, but nothing is
guaranteed. ufs does have a great track records and bunch of service hours
logged.

Example after a dirty shutdown:
fsck -y

That's actually a bit disconcerting, do you have hardware instability?
