It actually doesn't. Achilles has somewhat better stats and some melee bonus from Bravery, running ability, the chariot, and the shield, while Cu has Rune Magic, Disengage, two versions of Gae Bolg and superior attack speed (at least if we take Archer word for it). So a lot of uncertainties exist.
Can Kosmos actually protect against Gae Bolg? Yes, "a shield" can probably do it (I am still curious why this is mentioned only once and never ever comes up again) and Kosmos is an A+ ranked NP. However, the Barbed Spear that Pierces with Death isn't an ability which can't be represented by numbers (and it also can kill Arcueid, who is an extension of a "World" in some sense) so we have no idea if its magical energy enough to overpower the curse.
Can Achilles use two NPs simultaneously? If it's possible then he has a clear path to victory but if it isn't the case then he seems to come short when it comes to pure attack power.
So I tend to see it as a fight that might go either way.
