Well Issei may equal to Ophis at full power or even surpass her and even rival Great Red’s power in the future or not is depend on author.

But 1 thing that is a truth is Issei can become 3rd Dragon God! (Or 4rd if we think Ophis and Lilith are 2rd and 3rd or 5rd when Balberith become Dragon God before him!) XD
