Sakura's 3rd Databook speed stat is 3, Kimimaro's 1st Databook speed stat is 4.5. He would have presumably gained the remaining 0.5 by the 3rd Databook had he survived, so Sakura is not faster. She could have a temporary chakra-enhanced speed boost, but Kimiaro does not have to expend the chakra on such a boost, giving him a speed advantage. She is obviously stronger via punch/kick and can regenerate, but the toll on her chakra reserves could cause a problem. I think it would be a very interesting battle to watch, and as much as I like Sakura, I do not think she would be a clear winner. Either could win and it would not be by a large margin.
