I’d probably say Oryx. If it was based on their strengths at the time when we fought them Oryx would probably handily win. If it wasn’t I’d say it’d be in Oryx’s favor if he could just retreat like he did at the end of the Taken King campaign and force the battle into his throne world. The throne world gives him a huge advantage especially since I think, as a follower of the darkness, Nezarec would obey the sword logic and just empower Oryx there
