I would think the Noghri in weapons. Yinchorri are very large and strong, and can fight well, but Noghri are be faster and are great combatants.
Purely unarmed is likely different, though. Noghri simply may not be strong enough to do enough damage to their foes without weapon, Yinchorri are wookiee-big and have tough hides, so a likely result is getting in several good attacks before being taken down by superior strength and toughness.
