Prime Kabuto is the form he fought Sasuke and Itachi in, making him almost unbeatable with the exception of Izanami, probably the Totsuka Blade and Kamui (he wouldn't be able to get back from Kamui dimension). Other than that there is nothing he wouldn't be able to recover from.

Prime Kakashi would be DMS, meaning he can use Susanoo and has full Kamui abilities. As such he can become intangible at will and can transport himself to the Kamui dimension if the battle wasn't going his way.

Imo the only way Kakashi can win is if he can use the Izanami or can hit Kabuto with either Kamui or a Kamui-related attack so that Kabuto ends up in the Kamui dimension. Other than that, Kabuto's healing is too OP.
