The only dangerous thing about Shisui is Kotoamatsukami. All Kakashi has to do is use a shadow clone and trick Shisui into wasting it on the clone.

If Kakashi could keep up with version 2 Jinchūriki's, then he could keep up with Shisui's Body Flicker Technique. Shisui is also skilled at genjutsu, but so is Obito who used it to control Yagura, and Kakashi saw through his genjutsu, so that's not an issue against Kakashi.

Shisui being the strongest Uchiha isn't much of a title seeing as the clan was so weak they were killed by only 2 shinobi. Seeing as Kakashi beat Obito, i'd imagine he would do the same to Shisui.
