For simplicity, I would recommend using tar because it is a more common
format. There isn't much difference in backing up and restoring files
though ..

However, the dump format is slightly superiour in one way, as it can
handle advanced file attributes like ACLs that the tar format cannot.
Because dump works at a lower lever and has an understanding of the
underlying filesystem format, it can backup information that tar misses.
However, it is not much use on filesystems like reiserfs and NFS that
don't have a dump program ..
