Orochimaru does need to prep but if we are talking about bad Orochimaru, then his reanimations are the strongest possible and already kept in coffins for him to summon whenever he decides. If we're talking Orochimaru at his fullest strength and tools, Orochimaru wins without effort by using the Hokages alone which is possible as seen in the Manga and a little in the Anime.
