Very interesting.

To touch upon the matter, I once saw an interesting documentary on TV where they pitted a medieval Knight versus a Samurai, each with their respective equipment, and analyzed the data to find out who would have the upper hand in combat. The experts found out that the Samurai would most likely win because while the Knight was very well protected indeed, the Samurai's lammellar armor afforded him better maneuverability to overpower his adversary.
