Tsunade wins in power, Kakashi in speed and variability. If we're talking about Double Mangekyō Kakashi, it's a piece of cake for the copy ninja. One Mangekyō might barely be enough to chop the Sannin's head off. Apart from Kamui and Susanoo, Kakashi has no jutsu which can truly harm Tsunade, since she got the Byakugō and all.
