I saw this in the Chinese Naruto forums and will paraphrase here. The key motivation behind Sasuke joining up with Orochimaru is for power. It was never described what he did but presumably it involves drugs, forbidden nijitsu, and whatever, and the end result is you become a lot more powerful. You do dangerous stuff but in exchange you get mega powers. So far, so good.
Now Naruto is training hard on his own to prove that you don't have to do the kinds of forbidden/dangerous stuff that Sasuke is doing to become more powerful. So what does he do? He goes on some training that is only doable by people with an obscene amount of chakra, i.e. something only he can do. At his growth rate he'd be able to take on all 5 nations of the Naruto world at the same time in about a week, but where did the power came from? Was it because he was determined to save Sasuke? Nope. It's stated many times that no one else could possibly train like he did because no one else has the chakra to do it. It is hinted that he is training faster than normally expected because of his determination, but when you can train about 1000 times harder than anyone else thanks to Nine Tails, does it really matter?
So in the end Sasuke is right after all. He sure doesn't have Nine Tails bailing him out and providing endless chakra on demand, so going with Orochimaru was the best thing he could have done if he was to get his revenge. If Naruto doesn't have Nine Tails by his side their team probably would've been crushed 100 times by now already and Sasuke would have gone nowhere. Friendship sure doesn't get you very far in Naruto, unless you have Nine Tails with you.
I'm curious how everything turns out. At some point presumably Naruto's going to be beating a whole mess of people (some combination of Itachi/Sasuke/Orochimaru, probably all 3), except him winning has nothing to do with friendship or conviction or anything else. It is because he is special and gets to power up in insanely fast ways that no one else can even attempt.
I also really like all the times Nine Tails bail Naruto out of certain death, only to have Naruto say he is powerful now, no need for his interference. You can at least be nice to the guy that just bailed you out of certain death before declaring that everything is under control...
