Neji wins to be honest since Suigetsu haven't done anything impressive IMO. Even if we want to assume that the gentle fist won't work on him, Suigetsu still has no way of winning against Neji besides outlasting him which isn't an easy feat as well considering the fact that Suigetsu isn't exactly the guy with the most stamina.
Edit: Why is this discussion here and not in the Suigetsu vs. Neji thread???
Therefor, following logic, I'd say Neji is overhyped if we see his match record vs. what's actually said of him. Those who think so highly of him is because of what they believe he's capable of and what's been commented of him in the series. The same could then be said of Suigetsu. We haven't seen enough action per se, but he has been talked about and hyped to a certain degree. He was chosen by Orochimaru and then handpicked by Sasuke for Taka. That says something.
Oh, and don't get me wrong. I'm a big Neji fan. He should seriously get some showcase in the manga (though I like the comic relief he's dishing out :p). I mean, he got outshined by Chouji. Chouji.
Honestly, suigetsu isn't an issue on neji.. Neji's 64 strike combo with kamehameha is enough to make suigetsu a water pond. Neji can see his tenketsu, and when he use his gentle fist then it's over..
(even if it's just an anime, hinata seen the tenketsu of the water ninja, one of oro's experiment, with his byakugan)
Reasons are that eventhough Suigetsu can turn into water he must still have his chakra system otherwise he would always remain a water blob. So Neji can use his gentle fist to shutdown his chakra flow. And tbh the water blob tech is the only jutsu we have seen from him. And if neji gets caught in that its no problem. He will just use Kaiten and splash suigetsu away
Suigetsu has a tenketsu.. even if it looks like he doesn't have it, but still, in nejis's byakugan, he can see it clearly. Even all the bijuu, who are a mass of chakra, has still have it.. ( even if the anime is not a solid proof, but still we've seen that a water ninja like suigetsu has a tenketsu in their water from)
if he doesn't have a chakra system anymore then it is also logical that he doesn't have all the other parts that allow us to live and move and think.

His tenketsu turns to water. His chakra pathways turn to water.
As for him turning back to normal, remember his soul still exists. So does his mind (even if his brain doesn't), and his body has chakra in it, even if he doesn't have chakra pathways or tenketsu. Think of it like Gaara's sand. Even though it has chakra running through it doesn't mean Neji can poke it and make it fall apart. It's permeated with chakra, there are no little "touch this point and the sand stops working" spots inside it.
Even if Suigetsu doesn't have a chakra network he hasn't shown anything that can beat Neji so IMO Neji at the very least wins by wearing Suigetsu down.
If Neji has to use a constant amount of chakra to blow Suigetsu up or turn him to puddles of water, who do you think will run out of chakra first? Suigetsu's never been shown to run low on chakra just from liquifying himself, and we're allowed to give him a body of water in the tournament to make sure he's even harder to contend with, so I've no real reason to believe Neji has the stamina to keep blowing up a giant water monster over and over.
Well, based on what we have seen we have no reason to really believe traditional gentle fist will work on suigetsu any more than any other taijutsu. neji can hurt inner organs but what good is that if they turn into water on contact? In that regard the only real threat we have any reason to believe will have an effect on suigetsu is the tenketsu bit. Basically the only thing that might pose a real threat from neji as far as we know is sealing away suigetsu's chakra. Even then, since suigetsu's body is clearly less than normal would it be the same as with anyone else? Perhaps the location of his tenketsu is all wrong to begin with or they are hard to reach one he transforms into water. Even then, sealing suigetsu's chakra does not mean neji can kill him. When suigetsu took the biju bomb head on and was out of it he did not turn solid but rather he was still water and had trouble going back to a solid form. Suigetsu does not "transform" into water, he IS water IMO. Neji has a significant disadvantage IMO.
