CxC and EJOD are Ise & Vali's alternative to the JD. The JD seems more powerful because it's basically a berserker mode. Vali uses his demonic power to control it but as seen in volume 7, it still takes a toll on him mentally & physically.

CxC & EJOD on the other hand gives Ise & Vali more control to the JD's power. A comparison of how you can view it is: the JD is a broken water tap. It flows out uncontrollably. Now Ise & Vali put a stopper to that broken tap & control the flow of water coming out.

The CxC seems inferior because Ise opens the tap water in less amount while Vali opens his in more amount. So Ise pays less bill while Vali pays more. The bill refers to stamina or energy consumption.
