Well, in a fanfiction where they switch lives, Naruto would suddenly find himself in Sasuke's world of revenge. He might use his own positive attitude to try and change Sasuke's path from the inside. On the other hand, Sasuke in Naruto's place could bring a more serious and focused approach to Naruto's goals. He might train differently or interact with Iruka and Kakashi in a new way that could lead to some unexpected character developments for everyone involved.
In a fanfiction with Naruto and Sasuke switching lives, their skills and how they are perceived would change. Naruto, as Sasuke, might not be as well - liked initially in the Uchiha clan due to his different personality. But he could gradually win them over with his determination. Sasuke, in Naruto's shoes, would have to deal with the loneliness Naruto felt as a child. He might also approach the Hokage dream differently, perhaps using his Uchiha knowledge and skills to bring a new perspective to the idea of leading the village.
Well, it would be really chaotic. Naruto in Sasuke's body might struggle with Sasuke's more brooding and reserved nature. He'd probably be eager to show his friends that he's still 'Naruto' inside. And Sasuke in Naruto's body would have to deal with Naruto's boisterous energy. He might find it annoying at first but could also learn from Naruto's positive attitude towards friendship.
If Naruto and Sasuke switched places, it would be a huge change. Naruto might have ended up more brooding and focused on revenge like Sasuke. He would have had the Sharingan, which could have led to a very different fighting style. He might not be as open and friendly as he was originally. Sasuke, on the other hand, in Naruto's place, could have become more of a people - person. He would have had the Nine - Tails' power, which might have made him more of a target initially. But he could have also used it to gain the village's trust in a different way. Overall, the story would be full of different character developments and plot twists.
If Naruto and Sasuke swapped roles in fanfiction, it would change the entire power balance and their relationships with other characters. The plot could take unexpected turns and offer a fresh perspective on the Naruto universe.

He might struggle with the coldness that Sasuke often showed but also use his own warmth to thaw some of the Uchiha's colder relationships. Sasuke in Naruto's position would have to adapt to Naruto's simple yet powerful dreams. He could use his Uchiha abilities to make Naruto's dream of becoming Hokage more achievable in a different way. Also, their battles against common enemies would be very different as they would approach them from each other's perspectives.
If Naruto and Kakashi switched roles, it would be quite interesting. Naruto would be the experienced and calm sensei. He might teach his students with his unique brand of enthusiasm and his own lessons learned from his journey. For example, he could teach them about never giving up in a more structured way like Kakashi does with his training. The village might see a more energetic and passionate leadership from him in guiding the new generation of ninjas.

And Harry would be lost in the Hidden Leaf Village, not understanding all the ninja stuff. But Naruto could also show the wizards a different way of fighting, with his physical combat skills.
The story could progress with a lot of humor. Naruto might accidentally use Sasuke's Sharingan in a silly way, like when he's trying to eat ramen. Sasuke in Naruto's body would probably get into trouble for Naruto's over - enthusiastic behavior. This would lead to them trying to find a way to switch back as soon as possible while also dealing with the chaos they've created.
Naruto might have a hard time adjusting to Gotham at first. But his positive attitude could inspire some of the gloomy citizens there. He could also form an interesting team with some of the local vigilantes, like Batman. His ability to sense emotions could help in dealing with the complex and often dark characters in Gotham.

Sasuke, on the other hand, might use his knowledge to help the ninja world avoid future wars. They could also meet their younger selves and impart wisdom or skills that they learned in their original timeline.
