you couldn't be more wrong, one piece is far more luffy centric than naruto is naruto centric. All the strawhats exist to serve luffy and make his dream come true. Zoros entire character is based on serving luffy. Luffy always is the one that defeats the strongest and most important bad guy 1v1, outshining everyone, while the rest of the crew are fighting the insignificant subordinates.
Naruto is not like that at all, eg first fight against zabuza wasnt naruto beating zabuza 1v1, it was kakashi, naruto and sasuke all working as a team. Other characters were allowed to fight members of akatsuki, kishi let sakura and chiyo beat sasori and had naruto and kakashi chasing deidara and didnt even make naruto beat him, even had team guy fight him too. Naruto was not the one to beat orochimaru, one of the most prominent antagonists of the series, it was sasuke who killed him. It was sasuke who defeated itachi. If it was oda writing it, no doubt oda would have made naruto beat itachi instead.
