Short answer: the Neumann KH420 on measured accuracy, the Dutch & Dutch 8C on integrated cardioid DSP. The KH420’s CEA2034 spinorama shows an extended, flat on-axis response matching Neumann’s own published measurement to within 0.08dB, though horizontal beamwidth is on the narrow side at about ±55 degrees. The 8C pairs a 1-inch dome tweeter with an 8-inch midrange and dual 8-inch rear subwoofers. They are $1,802 apart.
Buy the Neumann KH420. It is rated higher for sound quality than the Dutch & Dutch 8C and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
