CMV: In the Naruto series, the idea that "Naruto is the hard worker, Sasuke is insanely talented" is flipped.

I know that among the fandom,  it's common to say that Neji was right and hard work doesn't matter as much as "fate". I more or less agree, but that isn't exactly what this thread is about. Now obviously,  both Naruto and Sasuke both work hard and are both talented.  However, I'd say if they each lean more towards one, they actually lean the opposite way implied by character statements. 

Sasuke - so obviously Sasuke is more than a little intelligent and he got some powerups. However, in comparisons with Naruto, Sasuke's work ethic seems underestimated by the characters. He literally spent the whole series training. Since the massacre, which happened when he was a child, he focused his entire life training to kill Itachi. Sasuke was certainly a prodigy,  but any child who dedicated every speck of free time outside of killer training school training to kill would be a killing prodigy.

Then, he graduated top of his class and got onto a team with jonin sensei who also focused all of his training efforts on him. Im not at all implying this is anyone's fault, but it still means Sasuke technically "worked harder" at this stage. 

Then, he decides he isn't getting enough training, so he goes to Orochimaru, and constantly trains for three years.
After that, he shifts to basically field training. 

Naruto - Naruto was highly disadvantaged,  but that wasn't due to lack of talent, and while he worked hard,  I'd say he didn't work as hard as Sasuke. We see at the beginning of the series that Naruto is bottom of the class and spends his time pretty much just fucking around pulling pranks. Despite this,  he masters shadow clones in a few minutes with no help.

Then,  when he gets on his team, he matches Sasuke in tree climbing,  and then gets unfairly ignored before the chunin exams. He spends his time fucking about trying to avoid Ebisu and then trying to help Jiraiya spy on girls before Jiraiya remembers to show him how to use his parentally installed nuke.

Then after spending three years training with Jiraiya (technically a wash with Sasuke's time skip, although I'd argue that the results and personalities of the teachers indicate otherwise) he realizes he's been born with so much chakra, he can just use clones to train faster without any real consequences. This allows him to master extremely difficult abilities out of reach of people stated to be geniuses. 

The end of the series is a wash since both end up fighting a lot and being given powerups willy nilly. However,  overall,  I think it's clear that out of the two,  Sasuke's hard work overshadows Naruto's, and Naruto is also more talented in terms of power due to birth circumstances.

Note: time=/=effort

Sasuke is a gifted learner. When he puts in X effort to his training, he sees Y reward in his abilities. 

Naruto is not a gifted learner. When he puts in X effort to his training, he sees <Y reward in his abilities.

In order for Naruto to  increase his abilities at a rate similar to Sasuke, Naruto must put in more effort to his training. This is why the idea that "Naruto works hard, training comes easy to Sasuke" is true.
