Well at least I'm assuming the speed was the same. The test would have no meaning otherwise.

I suppose for those biking on a basis of 4-7times a week, 80 RPM,although requiring more energy will least fatigue the nervous system. For once or twice a week riding, lower cadence/bigger gears are better.
So in this case the summary is:

If you're looking to develop aerobic fitness, go for 80+. If you're looking to develop muscle strength, go for 60 and a big gear.

Just common sense really!
