OK, my misunderstanding. Dropping the timeline back ten years, I'll still put my money on Dura Ace, although not by the large margin it was ten years later.

Back in 73-74, I had two main rides: The aforementioned all-Campy Gitane, and a World Voyageur that I modified somewhat for touring. Changed the wheels to sew-up rims (yes, for touring, they worked quite well, back then the difference between 27x1-1/4 clinchers and sew-ups were that vast), added fenders, bag racks, and a set of three Cannondale panniers. Both bikes had bar end shifters, the Gitane's was Campy, of course.

I still liked the Shimano Crane setup better than the Campagnolo. No, the action wasn't clearly superior like ten years later, but it worked as well, handled a much wider gear range (of course I had the long arm setup on the rear), and cost a hell of a lot less. Not having been the SunTour junkie like a lot of the guys I rode with in the Presque Isle Bicycle Club, I was a bit behind in catching on with the latest tech, but that Voyageur was the first indication I got that the Europeans (and especially Campagnolo) was in for some serious trouble from the Japanese like, right now.

At that moment in time, I still figured the Huret Jubilee was the setup to beat, but Simplex was still holding firm, and the performance of Shimano was eye opening. Things were definitely changing.
