Наруто because he has еще огонь power and еще durability. Not only can he easily destroy mountains in the Манга now but he can casually deflect mountain destroying blasts as well.
It's hard to compare Наруто with Bleach fully because nothing about the two Аниме is the same in any way..I feel it would be close but in the end I think Ichigo-kun would win.
Ichigo will kick Naruto's but. With his hollow for, flash step,bankai and getsuga tebshue that lil thing won't stand a chance... He beat ulqiorra, who's 10 times stronger than Naruto
