Being the leading power is about magnitude not intensity. The country that is twice as large and operates at a similar level of intensity will be the more dominant force (see also - China today). Per capita, I would bet on the Swiss (then and now) - though it will depend on the metric at that point and their output will be comparable to the Germans, British, French and the Americans.
