We have no idea of Shisui's abilities with Susanoo besides his in-game abilities. So that's hard to judge.

Koto is basically a one-shot. So basically Shisui can't lose. Unless Kakashi knew what Koto was and somehow knew when Shisui activated it. Since Mifune was able to disregard the jutsu once someone made him aware it was being use. But Kakashi doesn't know it, and he has no way of knowing when it's activated. So yeah, Koto gg.

Without Koto, I'd say Kakashi wins. He has SP chakra and can us some of his highest draining techs in quick succession. SP chakra basically wins this one. Plus since Shisui doesn't have EMS, using Perfect Susanoo would probably exhaust him after like 5 minutes. 10 tops.
