The least expensive that let's you sleep well. They all do a decent job of filtering oil. Even the orange can does a decent job of that. If your OCI is 4-6K you can get a very good Motorcraft for under $3.50, heck even for $2.22 in a Supertech at Wally World.
It looks like the new Amsoil EA filters are the way to go, of course if price is of no concern. They claim an absolute efficiency of 15 Microns, way better than any other oil filter now available. Have you considered a by-pass setup?
I had to think about this subject for a while.Unless you are going to greatly extended oil change intervals ,don,t waste the $$$ on the big buck filters. In my opinion there are better choices than the orange can.
My opinion is as follows:
Best oil filter - Amsoil EA
Best commonly available oil filter - Mobil 1
Best value/performance in an oil filter - Motorcraft
