okay lets forget apophis and just scale them up issei Pseudo dxd g and real dxd g

true form sirzech is strong enough that even Azazel commented that he could have easily defeated Hades, one of the Top 10 Strongest Beings in the World

issei with true dxd g is comparable with true form sirzech (not as strong but comparable)

issei Pseudo dxd g is on par with vidar with his boots, kicking techniques, and scale mail armor and strengthening magic to enhance his body would make vidar not only comparable to Thor (Top 10 Strongest Beings in the World) but surpass him.

so rather or not thor is stronger than hades (both are probably weaker than indra and shiva) is up to debate but issei compare them and that means that Pseudo dxd g and the real dxd g put issei in Top 10 Strongest Beings in the World. so real differance in power
