What an interesting argument...er...discussion this has turned into. Apparently everyone has an opinion on filters as they do about oil itself.
Speaking of opinions:
Cut a filter open- you can tell quality by the amount of media and its condition. If you don't see any dirt or metal it means it's still in your oil.
Does it have a bypass valve and anti drainback valve? Even if it does, the valve may open at a different pressure than the engine, transmission or whatever may be designed to handle. Yet another reason to go with original equipment parts.
If you wanna be safe, use what they call for. If you want to do better than that, become an engineer and design your own.
