Plus, Arima was a CCG prodigy since in high school-He even managed to defeat someone as strong as Yoshimura, though he was just 17 years old. Arima also did alot of practice with quinques as a kid, to the point where Fura accused him of not living a normal school life. 12 whole years of doing this constantly is what basically led him to be so perfect.

Kaneki on the other hand, was just a ghoul for 1 year, so he didn't even do much practice with his kakujya nor did he train hard in any other aspect of a typical combat...so he wasn't able to fully perfect the person he was expected to be.

Another key is learning to relax yourself and stay calm. We can see, it's obvious that Arima is able to do this, but Kaneki was overwhelmed by anxiety and emotional fluctuations, so he eventually slipped...thus he was vulnerable to Arima's wrath.
