Sasuke with his 3 Tomoe could mostly fight Kyuubi Naruto. At least, until Naruto pulled out a Tail.

So Kakashi with 3 Tomoe could as well. Their speed is most likely comparable too; Kakashi specifically had to train Sasuke's speed up to even use Chidori. So Kakashi himself had to have been that fast at least.
