Bear in mind, with Shadversity, he isn't a Historian, Smith, or any sort of actual expert, just a history buff. That said, some of his stuff his good.
There are not really any particular 'best' weapon styles or forms. Most weapons were developed to deal with specific threats and are the result of their culture, environment, resource level, and the threats they faced. For example, as much as we love swords, for most of history, swords were the weapon of wealthy elites who were most often fighting under armored peasants. They were great at cutting through light armors and clothing, but versus heavier armor or even chain, it was better to reverse your grip and swing them like a hammer. Because, like weapons, armor developed to meet the threats that weapons posed. Maces and Hammers were the weapons of choice versus heavily armored knights, for example, despite all stories and movies to the contrary.
Really it all depends on your time period and cultural setting.
