Personally I like the dry filters like AFE or AEM, no oily mess and good filtration. I checked my AFE drop in after 5k miles and the outside pleats/cloth were a little dirty (as they should be) and the inside pleats/cloth were clean, so it looks like not much dirt or dust is making it past the first layer. My MAF sensor and intake tube were clean too.
OEM still probably filters the best. I wouldn't go with the oiled filters just because it isn't worth the hassle or the extra amount of air you get, for the amount of dirt/dust that is let in (which actually probably isn't that much).
Good Luck with your search. Personally if I were you I would just get the Motor craft one and be done with it. No need to stress over air filters.
