ddrescue has more options for recovering data.  For example, when it
encounters bad sectors it skips ahead to try and copy the good areas of
the disk as soon as possible, then goes back and tries to recover more
data from the bad areas.  There are also controls over the number of
retries, disk access method (cached or direct).  Also, it can use a log
file (different to the --domain-log file) to record its progress, so you
can restart the program and it knows which areas have already been
recovered.  It doesn't know anything about filesystems though!  It's
nice to be able to combine the strengths of different utilities that
complement one another.
