I looked over their website and pulled a couple of numbers we might use to compare. I'm sure you've seen these, but I'll post for other's benefit.
The FS2500 states they are 2.78 micron absolute, which means they remove 99+% of particles 2.78 microns or larger. I didn't find anywhere on there that this was done at ISO 4548-12 standards but am assuming it is??
AMSOIL's EaBP filters, according to this ISO, has an absolute efficiency of 98.7% at 2 microns, and soot removal was determined to be a time weighted average of 39% according to test method ISO 23556.
How does that compare? FS doesn't state a time weighted percentage, but I did find this "dry" article on bypass filtration on luberfiner.com and 39% was the best they could achieve and was 3x better than their previous model.

Take that for what it's worth.
My take......these two systems are pretty much comparable as far as efficiency. What comes into play is what is the capacity of each filter(how long will it last)? And then cost differences?? I believe the AMSOIL system can run $100-$150 less from the quotes that I've seen, but would have to verify that.
Can't go wrong with either one
