Oh no, we're going to have to get into comparative analysis of magnetic performance taking into account can thickness.
I appreciate you doing the particle counts and agree that it is the best course of action to make determinations for your particular circumstances. And that it likely won't matter anyway.
Going off the BR data (which although it is flawed, I think for the high efficiency filters it is more usable), the worst performing leaf spring was apparently on the Royal Purple and I number crunched that it became a 91.3% efficient filter in the 21-38 micron range. That compares to 99.3% for the 20-40 micron range through Ascent's testing.
However, both Ascent's and BR's Royal Purple filter were metal on metal sealing. So either the BR Royal Purple was of worse quality or their testing was flawed. The BR Amsoil did perform as expected while the Endurance and Ultra were in between.
My own view is that since we can't see the size of the gap and the manufacturing has gotten worse, we don't know how bad the filtering performance will get. So while the current data suggests they are better than a Purolator Boss, in any individual case, it might be as bad or even worse than a Wix XP
