Royal Marines vs US Marines: Who's better?

I'm Definitely Staying Out of This Argument, My Father was a Marine, My Cousins Son is a Marine. My Basic Typing Instructor was a Gunny and My DIVO and ADP Chief on Adak were Marines. Marines Protected My Shop at CINCPACFLT, FICPAC, Adak and NCU London. Then again I Helped the Royal Marines Teach US Marines RIOT Control Procedures.
