I was never to impressed with the build quality of the Hasselblad lenses, but that is with limited use, and maybe I was expecting too much from such a vaunted system.
I would phrase it differently. The Hasselblad Zeiss lenses have very good build quality, but aren't always smooth. They are very robust, but the haptics are sometimes a bit crude.
But Nikon and Canon were photojournalists lenses, built to a cetain level of robustness. I was never going to throw my lenses into the back of a rental car, so I figured Nikon lenses (non AI) would last me a lifetime, which they are doing. And the build quality of my 2 ZF lenses are equal to or better to anything I've ever handled, rented, or owned. The Leica lenses I've owned were better built, but that comes down to materials, which you are paying for.
Apart from the helicoids of the Nikkors, which apparently wear out (I have never personally seen it happen), I would say that the Nikkors can actually take more knocks than the ZFs. I prefer the feel of the latter, and they are clearly more refined, but a bump in the wrong place could really mess them up, whereas the old Nikkors were just tanks. There are just so many levels to build quality it is hard to compare on a level playing field.
