With adamantium, it's not about strength; it's called a miracle metal for a reason, slices through damn near anything.
Creed's claws may not be as long or well-shaped as Wolverine's, but Aquaman is not even 100% bulletproof, so... pretty silly question.
Arthur needs to use his trident's elemental powers here (same powers that fanboys loathed and got the writer to abandon the comic), otherwise he's screwed.
