The Sharingan gives enhanced perception. Naruto would be able to see things in slow - motion, which would help him dodge attacks more easily. He could also see chakra flow better, allowing him to detect hidden enemies or traps. In addition, the Sharingan has different levels of evolution. Naruto might be able to unlock these levels over time, gaining even more powerful abilities like the Mangekyou Sharingan. This could potentially give him access to unique and extremely powerful jutsu, such as Amaterasu or Tsukuyomi. However, it would also come with risks, like the strain on his eyes and the potential for blindness if overused.
Naruto would gain the ability to copy jutsu. With the Sharingan, he could watch an opponent's movements closely and replicate their techniques. This would be a huge advantage for him in battles.
Naruto would gain the ability to predict his opponents' moves more accurately. The Sharingan allows the user to read the subtle muscle movements of an enemy, which gives an idea of what they are about to do next. This, combined with Naruto's own combat instincts, would make him an even more formidable fighter. He could also use the Sharingan to break genjutsu more easily. Genjutsu is a form of illusionary technique, and the Sharingan's ability to see through illusions would be a great asset for Naruto, who has faced many genjutsu - users in his adventures.
