Guys, guys, easy
Fact is Sasuke knows more jutsus than Naruto, and Kakashi knows more than both of them together (Copy ninja ftw). That said, we are talking about numbers and range of skills and elements.
Naruto is doing fine by making up lots of Rasengan variants. I believe in this because the advantage Rasengan has is the fact it has no element, or can be infused with types of chakra. Sasuke had both lighting and fire elements so in order to cover more match ups he develops many techniches with them. It's a given or he would be in serious disadvantage. Plus he has MS which gives him more techniches.
So if u let me I would make a comparison here. Element wise both Naruto and Sasuke has two: sasuke has fire and lighting (no neutral cause he never uses it, save do the spiderman tricks) and naruto has wind and neutral.
Naruto focus in the neutral cause that means he wont be at a disadvantage against any element, and it will be mostly a battle of which tech has more chakra infused. Sasuke on the other hand is a genius as stated many times (not a sasuke fan, but these are the facts) so when reAlizing he has 2 elements he developed both.
On other side of the story, Naruto has Sage and Kyubbi mode, which to be true, I find they are more Steroid base techs. If u have played MMORPGs u could say they are buffs. Sasuke on the other hand is gifted with the MS which wouldnt act as a buff but as more techines, so u cant really use the same balance to weight these two.
So while Sasuke is more like a Caster, Naruto is more like the Bruiser type. They have both advantages. If I can buff myself in energy and pummel someone with a neutral attack then so be it, name me one trick pony as u lay on ur back down my feet.
If I can cast "spells" which will beat 3 or 4 types of element as well as hypnotyzing and consuming my chakra at dangerous speeds then Ill laugh while u say Im a sissy I will still see ur ashes go with the wind.
That being said, Come at me Hater!
