Probably claws. It's long been vaunted as the highest DPS set of the scrapper primaries, and just got a few animation changes to augment that. However, unless you get to know and love your attack chain and slot yourself out well, it may not feel quite like the carnage it has the potential to be.
BS is primarily burst damage, and is up there in terms of heavy hitters of the scrapper primaries. DB and Kat are middle of the road somewhere, but Kat can be vicious in terms of DPS as proved by good folks like Werner. So it's a tossup between Kat and claws, really. Depends on how you want to build.
For base damage, it'd probably look like Starsman's Charts at 40% recharge. He has Dual Blades rated highest for sustained single-target DPS, followed by Claws, Katana and then Broad Sword.
At the insane top end, I'd rate them Katana, Dual Blades, Claws, and then Broad Sword.

Out of the lethal dmg primaries - Claws/BS/Kat/DB, which one does the most DPS in the mid to late game ( I am not counting slotting IO's or So's or DO's, I am talking base damage).
