You didn't finish the quote. He also said "If Anakin hadn't got all beat up, he could've beat the Emperor." That's more than Mace or Yoda could do. Also Gillard didn't rank Dooku so we don't know what he was. He didn't mention him as an 8 or 9 and common sense tells you he's not a 7. Again, I think some level 9'ers are better than others. Just because two people are both 9's doesn't mean saber skills become a moot point.
