This is entirely opinion. But by general census, most people would say Rinnegan is the best, then Sharingan, and Byakugan.
no, naruto has not got a rinnegan or any other eye technique
After Konan died Madara (Tobi) found Nagato's body and he transplanted Nagato's rinnegan into his left eye.
The eye techinque used by both Nagato and Pein/Pain is called Rinnegan
It depends on the situation. The Sharingan is known for its powerful genjutsu and heightened perception, while the Rinnegan grants a wider range of abilities such as the power of the Six Paths. Ultimately, both eye techniques are incredibly powerful in their own right.
Nagato controlled them, with the power of the Rinnegan eye, and the chakra receivers embedded in his skin.
Yes, when he takes Nagato's Rinnegan and puts it in one eye, his Sharingan in the other.
Nagato give pein the rinnegan
The rinnegan can do many things. such as give a person more chakra, more abilities, and people who possess the rinnegan have every chakra nature (fire water wind earth lightning). it can also put an attack of track like if you're about to stab them they can use it and you'll stab midair. i don' really know how it does that but I'll try and give that answer to you another time. people that have the rinnegan eye can also bring the dead to life with receivers embedded in them so that person can share their power, see the same thing, and control those people that you revived. as i have basically told you this eye is very powerful and can also put people through illusions and sense everything around them. the rinnegan is a purple eye with a ripple design. Two people in the ninja world have this eye and that is pein of the akatsuki and the founder of the ninja world.
You really think Konan has the Rinnegan!? Just for a simple saying , no , Konan does not have the Rinnegan as only Pain(Nagato)has the Rinnegan ever in the Ninja World.
He doesn't even have the Rinnegan
In the series, the Rinnegan is usually considered the most powerful ocular jutsu by the characters.
Nagato is the first user of the Rinnegan in naruto
