I don't think he is personally, though it is funny seeing all the fan made stuff saying he is. My sister actually uses it all to torture a friend of hers who loves Sasuke apparently.
I don't think he is because of what his brother said to him. Basically, Sasuke was told to live, live in a way that was focused on beating him, or something along those lines. So now he's completely focused on beating his brother, though from what I've seen, he starts to see some familiarity between himself (alone much of life, focused on goal of being able to beat brother, which means to be best) & Naruto (alone whole life, focused on earning everyone's recognition, by becoming Hokage AKA the best).
