This is a great answer. The Roman Gladius sword for example, was a short broadsword, designed for up close combat in close knit formations for the Legions. Great for thrusting, used in conjunction with a shield, yet not so heavy to wear the line infantry legionnaire out. So as many have already posted, depends on what purpose you want with one. I have two Knight swords on my wall, for looks. But if I ever had to use one for self defense, I would not pick ether.
