Okay not using it means what? He's spamming which isn't very well rounded. Sure he has it in his reserve but he doesn't use it, so he was a good ninja. Just not as good now with all this power.He's well rounded, he still has the ability to do the things he did in fights like the Deidera fight (use a wide range of moves and not depend on one attribute) he just doesn't do it now, or when he had MS. He's still a smart and well rounded shinobi in skill, he's just not utilzing it.
He was strong enough to not to die against the five Kage when he was spotted....well actually he was strong enough to not have A rape like a prison b****, just ordinary rape him, until Gaara showed up that is. Then Sasuke held his own for 10 more seconds against the other Kage...then he was being done in by Mei and almost obliterated by Oonoki BUT STILL...
You know what Idk where I'm going with this, he's strong and that raw power he had/has will/should allow him to do more then hold his own with Sasori and Kakuzu.
He's good. Let's leave it at that. Who do you think would win?
