These are two very different cameras.
I have an H5D and a Pentax 645Z.
Pentax is a more advanced camera. Shooting is easier and you can record video.
Hasselblad - has a different color and is more convenient.
If you recently started taking pictures - Pentax.
Simpler and cheaper.
But I will not sell my Hasselblad for long - if only I change it to H6D)))
Yesterday, at the request of my friends, I took two identical photos - on Pentax and Hasselblad. Here you can see how they vary in color. N4D may have a slightly different color, but they should be very similar.
