To answer this question, we first need to know the characteristics of the seven swords in the Taiwan Strait. The seven swords in the Taiwan Strait mainly include: sword, pangolin, purple wing, amethyst blade, purple inflammation, thunder and treasure. Each sword has its own unique attributes, so we can only judge which sword is the best to use from the specific usage scene. For example, if you want to solve a spiritual problem, then the sword is the best choice; Pangolin is the best choice if you want to face fast enemies; If you want to face a very powerful enemy, then amethyst blade is the best choice; If you want to attack a series of enemies, then Zijin Wing is the best choice; If you want to face a powerful enemy, then Yan Zi is the best choice; If you want to face an enemy with strong defensive ability, then thunder is the best choice; If you have to face an invincible enemy, then Shenbao is the best choice. In a word, the best sword depends on the strength and skill of the enemy you have to face, so you can't give a clear answer completely.
