Re: Naruto Vs. Sasuke....
Well Rikudo mode Naruto has some Raikage traits.
We won't know what kind of Powers sasukes' EMS will give him, but it will prolly be something to counter a few of Narutos' Jutsus .
Sasuke Arsenal ( just mentioning the big Jutsus) and how Naruto can counter em.
1. Amaturasu ( gets countered by Narutos' Speed )
2. Susanoo Arrows ( get dodged by Narutos' Speed )
3. Tsukiyomi ( Either Naruto closes his eyes and fights sasuke with Rikudo Modes Malice Detection abilities, Naruto using what he learned from Senjutsu chakra control he beats Tsukiyomi on his own. Maybe Kyuubi helps him ( that would be too lame) .
4. Kagetsuchi . Sasuke can do lots of things with this. I could see Sasuke covering his sword in amaturasu, covering Susanoo with it, or even using amaturasu like Gaara uses sand. ( Naruto counters this by using mid ranged attacks, Biju Rasengan, Kage Bunshins )
Raw Speed ( Sasuke counters' with his own raw speed or Susanoo + Kagetsuchi + Amaturasu.
Biju Rasengan ( Sasuke Counters' with Susanoo )
Raw Strength ( Sasuke counters with Susanoo )
Senjutsu ( Sasuke counters with his Sharingan eye sight, Fire Ninjutsus, Hawk Summons. )
Maybe Itachis' gift is the Jewel, that purifies the heart etc.
