Not physically but there personalities. Obito and Naruto were always the "losers" and weren't good ninjas. They have heart. Obito was always so nice and in the recent manga shows him carrying bags for a old lady. Obito is or was I think the nicest character in the whole manga. He taught Kakashi about friendship. As Naruto he wasn't a good ninja but he worked hard and he had the 9tails to make him even stronger in the future. Same with Obito if he lived longer he would of become an amazing ninja look at his eyes, they are what made Kakashi feared and his Sharingan is one of the most unique ever shown in the manga. Obito if he lived longer he would of been an amazing guy.
