The specs call for a parabolic shape, based on the diameter of the outlet and inlet. E is parabolic, A is not (or not clear).

The spec shape is the most efficient, where the orifice plate is the least efficient. Having an upside down curved inlet may make things worse, but there might be a resonant effect, depending on the flow rate, where the redirected flow may or may not interfere with the inlet.
