This is a common issue we see every time statements like this are made (Hashirama's comment on Itachi is a prime example), people don't take them at face-value & misconstrue them. While Kakashi has had had some opportunities to "kill" Obito, this does not make him stronger than Obito, people forget that Kakashi has had extreme amounts of assistance in facing Obito & has been saved twice now by Naruto & has also been revived by Kurama's chakra twice, which has allowed him to to perform feats far beyond what his true limits are as he himself pointed out, Kakashi's actual limits were evident in his battle against the Edo Jinchuriki, the only real power he has gained within his own natural limits since; is the ability to enter & exit Kamui's dimension at will, however as Obito pointed out this is also limited by Kakashi's chakra reserves, Kakashi is a powerful shinobi, but do not get carried away over a simple statement.shodaimeicon:
