FWIW (believe me) I would only go with the Edelbrock port for the simple reason the ECM can be located inside the passenger compartment. Under hood automotive is a hell hole and any complex electronics are at risk. OEM's have pretty well-established supply chains and are able to keep counterfeit crap components out of the production. Not so sure about the aftermarket.
