Motorcraft is the OEM plug. The engine was designed for use with the OEM plugs, so there really isn't anything better to use. Unless the OEM plug has been superseded with an improved version of itself.

What is your year, engine and model (Navi/Expi)?

That's what I was thinking about.

Does Motocraft make a better plug for a Ford than what it was originally spec'd with?

Kind of like "OEM On Steroids".

Your OEM spark plug number is: AWSF22E and the new number is: AGSF22WM
