The situation now is that Ishida goes unsealed. Meanwhile, Zaraki also goes unsealed.
Both have incredible overwhelming amount of power, but who would be the victor.
Please note that neither are allowed to be cheap(Zaraki pulling off a shunpo and cutting off Ishida's head while he is removing gloves, or Ishida firing an arrow at Zaraki's head because he has not fired his arrows at anyone's head so far, and I don't see a reason for him to do it now).
I put my money of Zaraki. While Ishida has shown himself to overpower Mayuri easily, I think Kenpachi can take his attacks. Afterall, Kenpachi has taken so many supposedly fatal attacks by Ichigo and Captains, I do not see why he would fall easily to Ishida's arrows.
zaraki wins imo.
The problem with Quincies is their kind of power source.
Shinigami take their strenght from the inside. Quincies take it from the reiatsu surrounding them. It is also quite clear that a Quincy can't absorb and convert an infinite amount of reiatsu for their attack. If the power becomes to big, they can't handle it and damage themselves.
So basically Ishida could take a huge amount of reiatsu from the surrounding area and probably use Kenpachi's huge reiatsu, too. The problem is here, that if he fires an arrow that still consists of a smaller amount of reiatsu than what Zaraki bursts out, the arrow will be rendered completely useless since high reiatsu attacks nullify those with a lesser amount.
It comes down to how much reiatsu Ishida can use for one arrow and if Kenpachi can withstand it.
But judging from the power Ishida displayed against Mayuri, I'm sure he could've pwned almost any captain at that time. Ishida seems to have the advantage on first sight since he is the distant fighter and Kenpachi isn't. It might be stressing for him but if he can do that final shot he dealt Mayuri at least twice, he has a good winning chance. Then again, there is another problem for the quincy:
I'm basing this one from what I see and believe might be true. Since Quincies don't have such a hight amount of reiatsu coming out of their bodies compared to Shinigami they might have problems withstanding someone who displayes a strong reiatsu. Ishida was shown to be almost shocked and shaking when Mayuri displayed his reiatsu after introducing himself and he is certainly not the strongest. Even though it was an anime-only scene, the same happened when Ishida, Inoue and the others arrived at Soukyoku-hill and were stopped by Ichimaru. Both Inoue and Ishida were pressed down to their knees when Ichimaru released his reiatsu.
That kind of leads me to believe that Quincy can't withstand high reiatsu powers since they don't have a strong source of spirit energy within themselves. This could play out to be Zaraki's advantage since he has huge amounts of reiatsu and the longer the fight continues the more it will stress Ishida's body and weaken him.
All in all I bet my money on Ishida since he can attack from the distant and is quite fast. If he doesn't engage in close combat and acts quick he can win this one.
mmm zaraki would win =D

Good thought, but there is a flaw: If yours is the case, then all fights would be completely pointless, since person with the lesser reiatsu would never damage person with the higher reiatsu, therefore, all fights would be totally meaningless, only one side bleeding, etc etc.
There isn't any need for your reiatsu to be at the same level or higher than the other's reiatsu to attack without nullified.
Whatever. I think that Ishida would probably win, even though we haven't seen any comparison, I think Ishida's full power unsealed arrow was the strongest attack we've seen this far.
Also, Kenpachi has got lots of disadvantages, he is a close-combat charger, Ishida is an ranged weapons specialist. It will be pretty hard for Kenpachi to get near him if he uses his movement techniques, since well... Kenpachi wasn't that famous for his shyunpo or speed at all.
Ishida's arrow TOTALLY PIERCED throught Mayuri's bankai (you know it's length) and then totally pierced Mayuri. Not, I don't think Kenpachi would've survived from this, no matter his reiatsu or greater constitution.
