Okay, assuming that my calculations are correct I would put Albion and Ddraig with power comparable to 8 Satan class beings. This is my opinion no one else's, and Sirzechs and Ajuka both have power comparable to 10 Satan class beings. I estimated that the four current Satan's altogether had power comparable to 22 Satan class beings and with only a quarter of Ophis' power that would be the equivalent of 32 Satan class beings. So using this information I suspect that Ophis' power is comparable to 128 Satan class beings, that's a huge difference in between the four current Satan's a difference of 106.

Remember none of this has been confirmed by the author or is accurate. This is all speculation and headcanon so please don't take any of this to heart.
