How would Artoria deal with Vergil? (How would Artoria deal with DMC Part 2)

In case anyone wonders what Part 1 was, it's the Saber vs Dante discussion. This time, the power gap isn't that massive, but it is actually problematic. Because Vergil is compared to Legends Darth Vader, and since Darth Vader in the Legends continuity could easily defeat Saber in canon, Vergil is whooping Saber's ass on this one.
