The plot. It has to be unique. Maybe it could involve a new threat that only Naruto and the Uchiha brothers can face together. This could lead to some intense and interesting team - up moments. Also, the way the fanfic deals with the Uchiha clan's history and Naruto's role in it can make it stand out.
A good 'Naruto x Itachi fanfic' stands out when it respects the original characters. For example, Itachi's complex personality, his loyalty to the village yet his love for Sasuke, should be accurately portrayed. Naruto's determination and his ability to see the good in people also need to be there. If a fanfic can build on these traits in a new and interesting way, like making them work together in a unique situation, it will be great.
A good Sai x Naruto fanfic stands out when it really explores their unique personalities. Sai is so stoic and Naruto is so full of energy. When a fanfic plays with this contrast, like having Sai be intrigued by Naruto's exuberance, it becomes interesting. For example, if it shows Sai trying to understand Naruto's unwavering belief in his friends, it adds depth to their relationship.
His abilities and how they are developed. If he has a power that is a combination of the traditional Uchiha powers like the Sharingan and something new, like the ability to control nature in a way no one else can. And if the story shows his journey of mastering these powers, it can make the fanfiction really stand out. In addition, the way his abilities impact the overall plot, whether it's in battles or in solving the mysteries within the Hidden Leaf.
