Frankly, I believe all the major brands (Amsoil, MG, Frantz, Gulf Coast, F/S2500, Oil Guard, etc) all work more than well enough for the application.
While I do believe there are some small differences, and particle counts would reveal these, the reality is that ALL of them filter down well past what is necessary to address what you're concerned about. They all filter with absolute efficiency far below 3um, and that is well below the typical range of damage from most particles (5-15um is the commonly accepted range).
I always suggest one picks a bypass filter based upon initial costs, maintenance costs, ease of installation, ease of service, etc. Comparing the efficiency of the bypass fitlers is a moot point; they are all so good that your engine will never know the difference, performance wise.
