The EOS-1D C has the larger sensor area. More area usually means greater light-gathering potential, though real image quality still depends on sensor architecture and generation.
These cameras were released 2 years apart. Consider sensor generation when comparing pixel metrics.
Amber marks the value that is generally preferable in this comparison context. It is not an overall camera score.
