It's actually not that easy to judge Lancer's weapon mastery. If your simply comparing by their first encounter, remember that Lancer was under the command spell and wasn't able to fight at his maximum power. And Saber was having difficulties fighting Gilgamesh because weapons kept on appearing out of his GoB, slowing her down. If it was simply a fight in pure swordsmanship, without GoB getting the way, there is little question of whether or not Saber would have demolished Gilgamesh in a swordfight.
