This is a question all on opinion.
Im a huge naruto fan but i think Itachi is better, my reasons:
1. Itachi possesses the sharingan
2. Itachi possesses the mongekyo sharingan
3. Itachi is an Uchiha, its in the genes
4. Itachi is suffocated himself with hatred, he is a true shinobi
5. He killed everyone in his village with help from Madara
6. He's trump card is Susano
7. Amaterasu doesn't die out until it's killed what it's meant to destroy
8. Itachi has far more experience
9. He was top of all his classes back at the acadamy and graduated before Naruto could ever dream of
10. Naruto only holds great power because of the nine tails and the ability to never give up.
itachi is better than naruto without sage mode but with sage mode naruto is stronger and faster
no itachi never caught naruto
itachi is in the lake where kakashi beated naruto in the first place
Itachi gives Naruto some of his power, though it is yet unknown what exactly the 'power' was.
There is no "they"...only Sasuke kills Itachi. And, no, Sasuke is not friends with Naruto.
no it is not it came from itachi but people say it came from naruto but is really came from itachi. (:
naruto doesnt kill itachi, sasuke does. Nor does Sasuke. Itachi was already dying until the battle with Sasuke. I think he had TBC.
Yes, Naruto eventually finds out when Itachi is resurrected after Sasuke kills him. Itachi is resurected by Kabuto's edo-tensei.
At first Itachi was stronger but Naruto learned more techniques so he is now more powerful.
No, they did not. Itachi died fighting Sasuke. Naruto and Kakashi were trying to find Sasuke at the time.
Naruto ado
finish the sasuke vs. Itachi battle and then you'll get itachi
