Kakashi still >> Yamato and Sai
But Sasuke prolly cwould create the same result
Idk. I think it'd be different. Let's say that all the Sannin are equal in strength in power. It's not improbable to think that Sasuke received the same amount of training that the other two did. Aside from Kirin, Sasuke pretty much had the same amount of training that Sakura and Naruto had. Naruto learned to enhance his Rasengan, Sakura learned to enhance her strength, and Sasuke learned to enhance his Chidori.
But let's say that their training did not equal Sasuke's training. Kakashi was still able to manhandle two of the Sannin's students at once.
I'm not a fool to think that Team 7 would have won with Kakashi--I mean, there's no chance he could have won against Orochimaru alone. But, I don't think that Sasuke would have tossed Kakashi around. I mean, he wasn't able to do that even with his Mangekyo Sharingan.
Honestly, I think all of them could have done better. Naruto froze up, Sakura was interrupted by Yamato. I believe this scene was to show that Sasuke was completely different from before.
