Ahhh, well you are among the first that has been able to answer that question with anything other than really vague responses. However, you add something in there that is vital. "The best bang for the buck". Which simply states that on a cost to effectiveness ratio SuperTech offers good filtration relative to its cost.
This, of course, brings up another point. A supertech filter for your engine may not have the same effectiveness on the next engine. I have stated many times that you could take two identical 3800 engines that came off the line one after another and the first engine may do okay with the SuperTech and the next one may not. Each engine responds a little differently to oil and filter combinations.
Most just assume because they had no issues using a particular filter that its a 'good' filter. When in reality the ONLY way to judge how the oil and filter are working is through oil analysis. Furthermore, the information provided by most manufacturers makes it nearly impossible to compare apples to apples with regards to filter effectiveness. The only way to really judge a filters effectiveness, from a consumer perspective and short of independent testing, is through oil analysis. And you still have to keep in mind that the oil itself plays a role. A motor oils ability to hold particles in suspension, resist breakdown, the additive package all play a role too. Use a crappy oil and it may stress the filter to no end with regards to trying to trap any debris and may load it up in a hurry and send it into by-pass mode.
Most also assume if its expensive, then it must do a good job and of course that is not always true. I have seen some rather expensive filters that when you press the manufacturer about the filters effectiveness you learn it only has an absolute filtering rating of around 40 microns which is just absolutely horrible.
But, again, I will commend you on the fact you at least inquired to someone that had some knowledge about filters and lubrication. I have done A LOT of oil anlaysis testing over the years and have seen some pretty crappy stuff. As well, every filter I pull off an engine gets cut open for an internal inspection, no only to see if the engine is throwing off some junk but to see how the filter itself held up. Which is why I detest Fram filters. Not because they have a bad rep, or because others have said they are no good, but because I have pulled my fair share of them off and cut them open and SEEN how bad they are.
