In the world of "One Piece," the swords Enma and Shusui are both highly regarded and possess their own unique qualities. Comparing which sword is "better" between Enma and Shusui can be subjective and depends on various factors. Here are some points to consider:

1. Enma: Enma is a legendary sword from the country of Wano and is one of the 21 Great Grade swords in the world. It was previously wielded by Kozuki Oden, a powerful samurai. Enma is known for its immense power and the ability to emit haki, a form of spiritual energy that enhances a swordsman's attack and defense. However, it has a reputation for being difficult to wield due to its immense power, and even skilled swordsmen struggle to control it.
2. Shusui: Shusui is also a legendary sword from the country of Wano and is one of the 21 Great Grade swords. It was previously wielded by Ryuma, a renowned swordsman. Shusui is highly regarded for its incredible strength and cutting power. It is a black-bladed sword with a distinct appearance and has become closely associated with Roronoa Zoro, who wields it in battle.

The perceived superiority of one sword over the other can vary based on personal preferences and individual strengths. Enma is known for its raw power and haki-boosting abilities, while Shusui is renowned for its cutting prowess. The choice between them may depend on a swordsman's fighting style, skillset, and compatibility with the specific sword.

Ultimately, in the "One Piece" series, the strength and effectiveness of a sword depend not only on the sword itself but also on the abilities and techniques of the swordsman wielding it. Both Enma and Shusui are exceptional swords, and their true potential is realized in the hands of skilled swordsmen like Kozuki Oden and Roronoa Zoro.
