Lol at people who think Sasuke wins.
Sasuke has shown no chakra control feats to even suggest he gets out of Temple of Nivara. Shikimaru and Sakura has chakra control better then Sasuke, demonstrated in databook and managa. Sasuke's experience being lower proves it that the databook is accurate for part 1 series.
Not only that but people think he will land a Chidori on him in the first place?.
Kabuto has a water source in this area. Even though he has shown using Suiton only in part 2 series doesn't disprove he could use it in part 1(plus the condition has change to beginning part 2 Kabuto anyway).
Since Kabuto knows how to use Water Release: Great Waterfall Technique[

]. Nothing is stopping him from forming it with a even bigger source at hand like Kakashi[

(P.S is it common for Kakashi ranking/level people to know at least two element[

I can make a list of more thing he can do. Sasuke stands no chance.
