Spectre would win this easily
It's not about magic. Spectre doesn't utilize "magic" persay. He just has a lot of authority in DC, his power derives from the Presence. The Presence is NOT magical in nature, the way Marvel has "Power Cosmic" is sort of what the Presence could represent in DC, only to a much higher degree.
The Presence is absolute dominion over every other aspect of DC's structure, the fact that the Spectre is backed up by presence means he can defeat any form of Superman easily.
Remember, its not about magic here
