Gaming on PSP emulator or gaming through emulation?

Why i would post this thread? I used to play a PSP game named God of War: Ghost of Sparta on my PSP emulator, but now i play it on my android game handheld JXD S7800B(for emulating games). To my suprise, the graphic and gameplay are better than that on my PSP. I do not know if you have the same experience. But all i wanna say is that emulation is good. What do you think?

I think the psp emulator has fewer bugs

but then again I only play RPG games so, those are pretty easy to run compared to action games lol

it works! but in my case my emulation is slow.
i tried different settings that make better than before but not so well to play.
