Those are not the same settings, and you can see the reason why in
this benchmark:
http://www.nongnu.org/lzip/lzip_benchmark.html""xz -9" uses a dictionary size twice as large as "lzip -9". This makes it
appear as if xz could compress large files a little more than lzip."
If you pass to lzip the same dictionary size used by xz -9, then lzip wins.

and so the comparison is fair enough : )
