It really depends on the writer's preference. Some fanfictions might have Naruto winning because of his unwavering belief in friendship and his ability to draw on the power of the nine - tails. Others might have Sasuke winning due to his strategic mind and mastery of the sharingan.
Naruto. His positive attitude and never - give - up spirit often inspire Sasuke. Also, his ability to connect with people gives them an advantage. He can rally support from unexpected places and his chakra is always a big boost in tough battles.
Most likely Naruto and Sasuke. In the original series, they were already very powerful when they faced Kaguya, and in fanfiction, they could be even more so. Their combined strength and determination usually make them the favorites to win.
In a lot of fanfics, Naruto is stronger than Sasuke. Naruto has always had an incredible willpower and in fanfics, this can be translated into him achieving greater power levels. His ability to make friends and allies can also lead to him getting more support and resources in the story. For example, he might get some special training from an ancient sage that Sasuke doesn't have access to. Also, his positive attitude can attract more powerful beings to help him out, which gives him an edge over Sasuke in terms of strength.
I like Naruto in these fanfics because he always stays true to his beliefs. He is constantly trying to bring Sasuke back to the village and is willing to fight for their friendship.
One of the best moments is when they have a rematch that showcases their growth. Naruto has become stronger with his new jutsu, and Sasuke has further mastered his Sharingan powers. The intense battle of ideologies during the fight is captivating.
It's really hard to say. At the academy level, Naruto has his raw determination and his unique ability to learn quickly. However, Sasuke has his natural talent and the early signs of his Sharingan powers. If it's a physical fight, Sasuke might have an edge because of his agility. But if it's a test of willpower, Naruto could come out on top.
Obviously, Naruto and Sasuke are going to be the main characters. Their relationship and how it develops after their fight is likely to be the central focus of the fanfic.
