That's true, but Sasuke puts himself out there more then Naruto.
Naruto and Kakashi vs Itachi
Naruto and Kakashi vs Deidara
Naruto vs Kakuzu (After Kakuzu had already fended off Kakashi, and Chouji.)
Naruto vs Pain (Would've have lost had Hinata not come down and got herself mortally wounded)
Sasuke vs Deidara. All Sasuke except for using his stolen summoning to survive Al qaeda no Jutsu.
Sasuke vs Itachi. Didn't win, but survived. Went to Itachi although he didn't have MS and knew he was weaker.
Sasuke vs Killerbee. This is his first battle with teammates in Part 2 and they did get they're asses KICKED. That's because they fought the Hachibi, the only Jinchuriki that had control over they're Biju and in the end, Hachibi retreated. Weather this was because Bee was bored or not is debatable.
Sasuke vs The Five Kage. This'll be my last one, yeah, got his ass kicked (again). That's because he's a wanted criminal jumping down into the middle of a room of the strongest in each village and starting sh*t. Naruto never got F'ed up so bad because he didn't bust into Akatsuki's cave and start trying to kick three kinds of ass at once. The only reason he survived was because of Tobi and Zetsu, but like I said, he kept losing because he was putting himself out there, something no one else in the series does. He didn't even flinch at the sight of Raikage and in the end, took one of his arms.
