I've never read a legitmate posting of early Campy hub failure that has anything to do with it's design. Some fools never do any maintenance and cause themselves problems, but that's user error.
Shimano tried a design that's similar to Campy with the 7800 model, but abandoned it after 2 years. The problem with the Shimano design is it does not allow for deep aluminum splines on the cassette body (to reduce weight). The shallow splines need to be made of heavier steel or Ti to have decent longevity.
Every brand I know of, other than Shimano, uses a design that works just like Campy's. The bearings that support the weight of the bike and rider are inboard of freewheel mechanism. Obviously, the design works.
