Many factors are involved in calling one filter better than others. One thing comes to mind is the amount of filter media in a filter. If you cut some different brands apart you will see the difference, of course, the type of filter media is just as important. Other factors can be cleanliness (metal cuttings in machined threads), burst strength (cold starts), leaks (o-ring seal or gasket). Personally I think regular changes with good quality oil and filters can not be substituted.
