At the time, Campy had the cachet but the Dura-Ace stuff is pretty nice. I wouldn't mind tracking down a complete group on a bike.
The first generation Dura-Ace derailleurs are marked crane though. Dura-Ace had at least two advantages over campy: the crane long cage rear derailleur is pretty nice and functionally I like it better than the first gen campy rally; the Dura-Ace crank is 130 bcd so you can go as small as the 39 up front.
