Both exhibited genius. But based on who was more productive, ingenious, and innovative....who would get the nod as most sucessful?

Coming along late to this, but you're joking... right?

The poster who said this is not even a fair question has it right. Ruger's and Browning's accomplishments are not in the same field.
Browning was an inventor - a visionary and mechanical genius who, fortunately for us all, applied his gift to firearms. Ruger was a businessman.
In his field, Browning was incomparable. He virtually destroyed his competition whenever he chose to create. Sometimes, he was so advanced he had none. The business accomplishments of Ruger are fairly ordinary - though, of course, admirable.
