William v. Peter the great.

I think Peter the great was the better of the two. only because he completely modernized Russia. he did, in one lifetime, what took most of Europe a few century's to figure out. now, granted, he learned allot from the french and the more sophisticated of the empires. but he built Russia into a super power that lasted. Prussia was strong yes, and revolutionized organized warfare. but their strength was short lived. where as Russia carried on.
