First of all, I think Luke is somewhat underrated. He can do more than just fight with a sword and pick locks. He can vanish into thin air (as shown in The Lightning Thief) and he can summon objects, such as furniture or a pool of water (as shown in The Sea of Monsters and The Titan's Curse, respectively). Both of these come from his being a son of the god of travel.

Given that, I would like to say that Nico probably has a better chance -- he even confronted Luke while he was Kronos. Summoning undead that can only be destroyed by a child of the Underworld - Luke would have no chance. And correct me if I'm wrong, but doesn't Stygian iron have the power to reap souls? That's something Luke could only counter as Kronos, when Backbiter took on its true form.
