The Linux kernel's choices of filesystems all have strengths and drawbacks.

ext3 is robust against minor hardware faults. It however can have its 
directory and some file data messed up real bad when it crashes or 
encounters power failure. I have had to manually go through mail queues 
to see what can be salvaged before deleting the entire lot. This is 
still better than XFS where I don't even bother looking for salvageable 

ext3 never matched XFS' performance though...so it is pick your poison.

I guess the best thing is probably to get a battery backed up NVRAM 
device to use as your external journal and run with data=journal with 
ext3. This ought to run all other filesystems out of town in terms of 
performance and integrity for many cases.

The Linux kernel positively needs another filesystem.
