Well Sirzechs and Ajuka's Demonic Power should be about equal though. They just have different traits. Sirzechs with the Ultimate POD while Ajuka with the Ultimate Technique.

As for Rizevim, not much is known for now, but since he's SG Canceller got nullified, we might see more of his abilities soon. Hopefully we'll get to see Sirzechs, Ajuka and Rizevim fighting in their full strength.
