Sasuke fanboys. Sasuke fanboys everywhere. Just some things to clear up.
1. The fight Sasuke VS Danzo wasn't exactly fair:
a) Danzo didn't go all out because he knew he would have to deal with Tobi after defeating Sasuke.
b) Karin actually helped Sasuke. If there was no Karin, Danzo would not take her as a hostage and wouldn't give Sasuke an opening to stab him.
c) There was also a moment in the fight when both Sasuke and Danzo collapsed and Sasuke was only able to get up because Karin helped him. Danzo, on the other hand, managed to get up with his OWN STRENGTH and if it wasn't for Karin, would finish Sasuke off.
To sum it up - Sasuke would be almost raped by Danzo in a 1vs1 scenario.
2. And now onto the fight against Kakashi...
a) Sasuke was healed by Karin.
b) Kakashi still had doubts about killing Sasuke.
c) Sasuke started going blind because he OVERUSED MS. People say that he can spam Amaterasu and that's why he would defeat Kakashi, but there is a trick here. The more Sasuke spams MS, the faster he gets blind. The fact that he went blind against Kakashi is ONLY HIS OWN FAULT and the COST OF USING HIS JUTSU, so it should not be treated as a handicap.
It's like saying about the lastest chapters: "Oh, Kakashi would rape Tobi solo, but he was handicapped with eye bleeding and collapsing!".
3. Now's the time to compare their abilities:
Raiton: Kakashi takes it, Raikiri>Chidori, Kirin is of no use to Sasuke (Kakashi can cut a lightning in half with Raikiri, stated in the manga. Also,), and in raiton jutsu variation would be a draw, since both have some modified Raikiri/Chidori.
Ninjutsu: Kakashi, hands down.
Speed: Kakashi keeps up with 6th gated Guy, he takes it:

Intelligence: Kakashi cracks Tobi's greates defense, whereas Sasuke spams MS like shit, in all love for his brother wants to destroy what Itachi wanted to protect and told Kakashi to bring back to life Itachi, whom he personally killed.
Taijutsu: Probably equal.
Genjutsu: Probably equal.
Stamina: Sasuke takes it, he's a full fledged Uchiha.
Did I forget about anything? Anyway, the score is 4:1 for Kakashi.
Edit: Oh, and Sasuke is better with MS also. But it has its cons and it alone is not enough to handle Kakashi. 4:2 for Kakashi.
That's it for now.
Yeah, I can imagine 4 or 5 arrows in quick succession:
<Sasuke shoots first arrow, Kakashi kamuis>
<Sasuke gets blind and shoots 5 more arrows in random directions, as he goes more and more blind with every shot.>
Add to this the pain Sasuke feels and it might even get possible for Sasuke to shoot himself.
Edit: Lol, misspelled Karin as Kirin. Maybe I should go to sleep.
