Anyone?
Well, since I'm bored I'll give my thoughts on the match. I'm not sure if I can vote being the OP, but at least I can point out something here and there.
I believe Sonic has this 7/10.
The reasons why:
1. Superman's biggest advantage in this match is his supeior speed (Omnipresent > Infinite), however, Sonic has already fought and outmaneuvered an Omnipresent being (Alf Layla wa-Layla). So yeah, I wouldn't call it an advantage against him. Really.
2. Sonic has an edge in both, AP and Durability. While he has a solid
Universe level+, Pre-Crisis Superman has "
Likely" Universe level+.
3. Sonic's stamina is limitless, while Pre-Crisis Superman has this:
Stamina: Incredibly high but has been shown to tire when fighting incredibly strong opponents. I bet someone here will get tired.
4. Powerful hax. Darkspine's "Time Break" was strong enough to affect an extremely powerful entity such as Alf Layla wa-Layla. Superman certainly wouldn't be an exception.
P.S. It is stated that Darkspine Sonic has reality warping abilities, however, that's not entirely true. At the end of "Sonic and the Secret Rings", Sonic only had power to restore 3/7 worlds within the Arabian Nights. The worlds linked to the world rings in his possession respectively. He forced Erazor Djinn to restore the other 4/7 worlds with his second wish after the battle against Alf Layla wa-Layla. In other words, Darkspine Sonic can't perform any reality warping out of the Arabian Nights, once such power only affects said world/reality.
