If these two were to fight who do you think will win? I think Tobi will because he is able to stop Sasuke's mangeko (sorry if I missed spelled it) sharingan.
We all know that Naruto has the "i'll never give up" spirit, but I think he should just give up on Sasuke, who by the way tried to kill him at least twice. Sometimes I wonder if Naruto knows when to give up.
