If Juuzou is fully human (I believe that he is….after all, Bujin is and we know that a very small percentage of humans are basically OP’d), then I would say that Juuzou has more ability relative to his species than Arima does. However, Arima accomplished quite a few things that Juuzou has not. Aside from rank and sheer ability to climb ranks, Arima also defeated a ghouls without any form of quinque (with an umbrella, no less). Also, Arima defeated ghouls with more ease than Juuzou. Juuzou is an incredible agent, and I would be terrified of him if I were a ghoul. However, he isn’t as efficient as Arima. It could be a matter of style…Arima moved in straight lines, while Juuzou moves in curves, but whether due to pure physical strength or experience, I would say Arima had objectively more ability. 

I guess it depends on whether or not you give Juuzou extra points for doing so much more with so much less. He doesn’t (presumably) have the benefit of ghoul genes, nor does he have the “benefit” (at least, benefit in terms of fighting ability) of being literally raised to be a soldier. He also lacks the muscle-building and height-increasing benefits of testosterone. In other words, he’s less educated, less physically substantial, and less experienced, and yet still he’s managed to reach the highest possible rank, has won multiple awards, and has trained a squad which has won awards. 

So perhaps relative to both his species and his circumstances, Juuzou has done better than, or at least equal to, Arima. However, objectively, Arima (at the time of his death) was still the stronger agent.
