CxC is seemingly inferior to JD because CxC retains the sanity of the user, JD doesn't.

CxC retains Ise's sanity so Ise doesn't reach the point where his breaks his limit too far till his life energy is used to power-up the CxC, once Ise's stamina is up he would be unable to retain that form. The JD doesn't have that limiter. JD makes the user insane, so the user simply goes berserk to the point where they past their limits and the life energy gets consumed too.
