I don't know the detailed specification of the Dark Hero. As far as I know, the memory clock support of the Dark Hero is even higher - up to 4866, 5000 or 5100 MHz and has a pure PCIe 3.0 x16 slot. The Formula has more ports for air cooling. As well as one more port for Liquid Cooling. I assume that the differences are very small. I don't cool the VRMs (yet), but the rest. Everyone has to decide for themselves whether it makes sense. The 5950x runs very well on this board.
You can find a comparison of the three boards here:
