All depends on Kamui usage. If Kamui is not being used, I see Zombie Duo winning.
Darui's performance against Edo Kakuzu (doesnt matter if majority is off screen, we have context for behind the scene) was poor. And makes a clear indication of him not being able to take out someone like Kakuzu alone.
With that said Hidan's performance clearly indicates he can give the same treatment to Darui that Asuma had in Close-Mid quarters. Even then, Hidan is being backed up by a Raiton Mask this time. If one wants to argue these Mask are sitting ducks to Darui's Ranton, then Jingou coating on Hidan would be perfect use[considering it has feats to stitch people up or

]. Then its a done deal.
Another thing to consider is to think its fair to assume Kakuzu knows how to channel chakra natures into weapons? It was stated he can use all 5 nature, and manga states at high level. If thats the case Hidan would be more dangerous with Raiton Mask armor then I thought he would be.
-Kakuzu uses pressure on Kakashi with Katon+Futon Mask like in canon, until caught.
-Hidan takes out Darui with Raiton coat.
