What I Am Going To Post

I have recently come back to JetPunk after 5 or 6 years, and a lot has changed since 2015. I have undergone a transition from my ways of old, and have decided to focus on accurate quizzes that mainly focus on famous royal families such as the Houses of Hohenzollern and Hapsburg and also fictional groups such as the Skywalkers or the Hobbits.

One question after all of this: Who was a better king?

Frederick the Great

or

Charles V, HRE
