In relation to Naruto's progress compared with Sasuke, he still has a long way to go. Let's compare the two:
Sasuke has/wields/uses/can do/has an amv playing the in the background to....
-His nature transformations. He has fire and lightning, both very aggressive natures with high power techniques. Particuarly the lightning gives him a increase of speed/sharpness to his attacks.
-Eternal Mangekyo sharingan; aside from being a sharingan, and a mangekyo, he has THIS. This has to be one of the most efficient things in his arsenal. I mean Madara had one himself and has managed to stay alive for about 500 years, so it probably has more powers than Tschuykomi, Amateresu and Susanoo (which are all beast techniques in their own right)
-High intelligence. He may be a bit blinded by revenge but he's no idiot.
-Experience: he's trained with and killed Orochimaru, been on numerous missions and in many battles, and has taken on the Kages at once (even though he got pulverised, he didn't die which is a testimony to his skill; most people would have died against a kage alone)
-Highly powerful genjutsu techniques. I don't need to go into huge details about these, but he is very powerful with these.
Naruto on the other hand.......
-Has his own nature technique: wind. This defeats lightning, which is a plus against Sasuke. I have a strong suspicion that Kishi will give Naruto water as his secondary one because it would cancel out Sasuke's fire techniques, and Uzumaki means 'malestrom' (which has water and wind. Gettit?!?!?!?)
-Sage mode: An absolutely beast mode of power which not only has he mastered to a higher degree than Jiraiya, a sannin, but has utilised it to using his own powerful techniques. It gives him increased speed, strength and durability, whilst granting him the use of frog katas.
-Summonings: in a similar fashion to Jirayia again, he can summon the toads to his aid - Gamabunta is pretty strong!
-Experience: being taught by Jiraiya, Kakashi and deafeating various high profile ninjas such as Kakuzu and Pain, plus all the missions he's done, Naruto isn't a noob. And now he's training with Killer Bee he's going to gain a better scope on the ninja world from not only another jinchuriki, but someone who's from a different village who uses a different style.
-Tailed fox: One of the biggest assets he has, which after he has managed to control, has now access to being able to sense negativity, faster than the Raikaige (in a life threatening moment of determination) and amazing strength, the fox's power is immense. He's probably going to be able to learn the Tailed beast bomb, and some other jinchuriki abilities from Bee. But even without doing so he's very strong in the current form he's in. Maybe he'll be able to fully transform into it?
-Rasengan: his Dad's technique, which he has managed to adapt to different cirumstances and ways, it is a very powerful technique and the counterpart of Sasuke's chidori. After it's development into the Rasenshuriken, it's now insanely strong, although very chakra exhausting, and efficient in destruction, again cancelling out Sasuke's lighting abilities.
-The power Itachi gave him. We don't know what it is, but will know doubt combat Sasuke/Madara in some fashion.
We all know there's gonna be a big final battle between Sasuke and Naruto, and it's drawing closer. I'm hoping Naruto will develop himself more to combat Sasuke - at their current standing I think Sasuke is maybe just a bit stronger. But Naruto still has time to build his abilities up. What do you guys think??
