For a rear wheel with any amount of dish, it can make sense to use a heavier gauge spoke on the drive side and a lighter gauge spoke on the non-drive side. The lighter gauge spokes will stretch more for any given tension and thus lose less tension (from their already limited tension given the wheel's dish) when weighted. By reducing the chances of the non-drive side spokes going slack you greatly reduce fatigue on the spokes and should increase spoke life as a result. So, my answer would be both spokes used together would be best.
