dunno about that, Kratos>Dante, and Xemnas to the words of some has minor reality warping, enormous power and speed overall against Sephiroth who is a barely enhanced human...
Kain and Demitri are much more than mere vampires, as Sephiroth is much more than an enhanced human.
Yes, Pre-Nibel Sephiroth(his weakest form) was an enhanced human, but after falling in the Lifestream and gaining it's knowledge and wisdom, together with the fact that he completelly merged with Jenova "to complete his revival"... It's absurd to call him now, a mere enhanced human.
Pre Nibel Sephiroth was still capable of summoning supernovae, moving at godly speeds and possessing a nice range of materia at his disposal. I don't think there actually is a version of Sephiroth that qualifies as a barely enhanced human.
most of those things you mentioned are gameplay. Sephiroth never actually cast a canon supernovae and materia are not bound to the person meaning in a debate Sephiroth would only start with HIS equipment, since Materia can be anyones he wouldnt have any materia.
Actually, even if you wanted to completely disregard everything that takes place in the setting of a gameplay battle, the summon is recognised as his ultimate attack throughout the game world by members of his elite fanclub even by Crisis Core times, and as for the materia, as with his regular equipment, if it's something that he's consistently shown to carry on him, then by the unwritten rules of versus debates he should have access to it.
when is he consistently shown to carry it? how many times does he carry the same materia, he uses none in Advent children, his strongest incarnation for example.
most powers he uses are gameplay tbh and we dont even know if he has all the same powers in his current form (the one in this battle) anyway.
The most powerful materia featured in the game -- supernova -- is something he factually possessed in his arsenal, his preternatural speed, strength and agility can all be seen in cutscenes as such, he was capable of walking right through one of Ifrit's fire attacks (again, cutscene), and again, I'm talking purely about his pre Nibel incarnation.
Just to be clear, the "if" I was referring to would be this one:

The guy changes a lot through his games, what games does he have Supernova in and in what forms? and before you mentioned strength, whats his incredible strength feat?
He obviously acquired the materia sometime during his career as a Soldier, seeing as how by Crisis Core times he's recognised as possessing it. The only other piece of media it appears in is in the original game during the final [gameplay based] battle.
As for strength, he was capable of entering a sword lock against two other first class Soldiers at once, one of them (Angeal), a being capable of effectively wielding the buster sword in combat (a weapon most humans would struggle to carry, let alone wield effectively in battle), and later on in the same battle enter another sword lock with the very same Angeal and overpower him by forcing him back. While it might not seem like such an obvious supernatural feat of strength, it still counts as a somewhat strong (in the sense that it's clearly beyond regular human physical based strength) showing in the department.
