I would say it is about Ajuka's power at least. He managed to beat Apophis, a Heavenly Dragon Class Evil Dragon, with it, so it was pretty darn strong. Although, even then, Ajuka would still be able to toy with Issei, probably, so he won't have a chance at all. However, power-wise, they would be about equal, I think.
