HiIt depends on what you need - I can't answer for you.
If you want the best of both get a H6d-100c or a Phase One.
Used HC lenses have the same problems as any used lenses - have the seller check the shutter count.
If the shutter fails, it will cost about $1800 to replace from Hasselblad (but you'll get a new warranty).
If the autofocus fails, about $400 if it's a worn gear (most likely).
They are supposed to be good for 150k (I think - I don't remember exactly - it's a big number)
But I did have a 100mm where the diaphragm started getting erratic that had only 80,000.
Otherwise I've had no problems, but I don't shoot thousands.
I asked Hasselblad for their repair costs for different parts and found that the shutter replacement on lens is ~700$, but not 1800$. I do have their official price list.
So if that happens is not a small but either not a big money to spend on repair.
The H5D is old firewire connection, and I don't have old Mac to run it on tethered so, sadly, either to buy old Macbook or skip to H6d or to Phase one IQ 60 which has USB. They also confirmed the all H models are still and will be serviced.
I also got suggestion for Fuji GFX 100S, better mp and DR but not a significant different look from full frame DSLR.
