Default APC E- Props VS Standard APC pattern props

Why are we using the Electric style APC props on electric powered pattern planes rather than the standard pattern props? We are turning the electric motors at comparable RPMs to a glow engine. The standard pattern props are stiffer and should be more efficient it seems to me. What am I missing? Anyone compared similar E and standard props in the same sizes? What results did you find?

Without getting into all the technical details of camber, under-camber and blade profile, the biggest issue is that e-power props do not need to withstand the "power pulses" of IC engines.
