I think the consensus is that a properly made sword, in the right modern steel, with the right geometry will survive most anything a sword should encounter in a sword fight. In battle today, if the man with the sword meets a man with a gun, the sword's attributes are irrelevant.
Since sword fighting is not a current issue, this discussion of X vs Y vs Z is sort of like the arguments I see online where people are seriously discussing if Superman and Batman had a fight who would win (Oh wait, they actually made a movie about that argument!).
