Neither. I'd preferably be the warrior class who has a relatively higher standard of living than the average peasant.
But to choose royal or peasant?
I'd try being a royal been a peasant a lot of this life.
I'd be constantly surrounded by the best and most loyal warriors. They will definitely protect me because if I die, they can say goodbye to their privileged lifestyle.
Once knew a guy who used to be the chief bodyguard of a certain pro Marcos congressman... he told me he had constant gifts and bonuses. One was a gold ak 47. And he had 5 luxury cars.
