If you mount ext3 with the data=journal option you may have better
recovery.  See the man page.  data=journal is what ext3 used to do but
the default was changed to give better performance.

My experience with jfs was good.  I never had the system die (not be
able to recover) and I don't think I ever lost data (I too don't have a
UPS and I used to live where the power was very unreliable).  JFS
recovers fast (a design criteria).  However, do a google search on
lists.debian.org for JFS and read the thread where it has been
discussed.  In the midst of that thread, I received an email from the
maintainer of jfstools which forwarded an email from the one person at
IBM who is left to watch for bugs: he was recommended agains JFS for new
projects since IBM pulled the rest of his team off of JFS.
