NARUTO -ナルト- because he has もっと見る 火災, 火 power and もっと見る durability. Not only can he easily destroy mountains in the マンガ now but he can casually deflect mountain destroying blasts as well.
It's hard to compare NARUTO -ナルト- with Bleach fully because nothing about the two アニメ 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
