What kinds of stats does Soul Calibur boast?
Speedwise (since that's the easy part) pretty much everyone should be MHS to some degree from being able to react to Sophitia and Cassandra's lightning. Though top tiers should be relativistic to lightspeed from being able to react to and block light summoned by Elysium.
Powerwise... that part's very much debatable. At least, pretty much everyone should be planet level+ to some extent due to the many,
many statements that Soul Edge is capable of destroying the planet (and the Astral Chaos, which itself is also partially within Soul Edge, being able to create worlds just as it can destroy them), not to mention Soul Edge being able to seemingly create planets and other celestial objects within the Astral Chaos. Pretty much everyone scales to this, whether it be direct scaling (Siegfried himself beat Inferno without Soul Calibur or Requiem as far back as Soul Edge/Blade) or from scaling to someone else (i.e. basically the whole cast scaling to Kilik, Siegfried, Sophitia, and the Conduit, who all fought wielders of Soul Edge)
The hard part comes from this old-ass statement going back to Soul Calibur 1, which only appeared in the official Japanese site which, in the middle of it, states that after the gods are destroyed and regenerated, the universe is born. Also implying the gods are destroyed all of existence (which likely means the universe) is destroyed.
Furthermore, Azwel, who specializes in research of Soul Edge and Soul Calibur, directly compares the Conduit's current power at that point to being "almost comparable to the gods". It's worth noting the Conduit gets stronger by this point, only being able to defeat Azwel by calling upon one of the two swords, and is still inferior to a good chunk of the cast.
Probably the more important comparison, Olcadan (who is a peer to Edge Master and just as ancient) believed himself to be capable of challenging the gods, and even views the two swords as rivalling the power of the gods themselves. This is during Soul Calibur III, before the two swords reached their full power during the events of SC4.
Ultimately? It depends. Depending on how you interpret the god stuff, then it's universal on scaling alone. Otherwise it's sitting neatly in planet level.
