I did a relatively short filesystem comparison when I moved my BackupPC
pool to another set of drives.  The high level results:

jfs, xfs:  quick, stable
reiserfs:  not stable
ext4:      slow
ext3:      very slow

The "not stable" designation comes from power-off-during-write tests. 
Other filesystems generally handled this gracefully, but reiserfs
corrupted the entire tree, and the recovery tools didn't get it back
intact.
