I think Motorcraft is generally a lower-tier filter, depending on the application. Most do not use silicone ADBVs and most also use standard paper pleated media. The ones that do use a silicone ADBV are, certainly, a step above the others.
The Fram Tough Guard, which I agree is a mid-tier filter, differentiates itself with a stouter (and probably more efficient) media and silicone ADBV.
