Motorcraft is good shit. I don't specifically know about their air filters, but I know their oil filters are just OEM rebadged Purolator filters, basically the best there is.
No need to lose sleep over choice of air filter as long it's a OEM spec paper filter unless you live in a dusty desert area. Just grab whatever you want. Good rule of thumb for filtration test is to hold the filter up to the light and see how well you can see through it, and the more pleats the better.
More pleats = more surface area = less vacuum on the filter element with a given filtration density = less restriction, less things sucked through the filter, less chance of sucking up water if it's near the ground. eg: look for thicker (darker in light test) paper with more pleats. That's the primary reason cone style filters are popular with aftermarket intakes: more surface area without needing 2' x 2' for an equivalent panel filter, less restriction without sacrificing filtration quality.
