From the outside, this filter looks pretty much identical to the PurolatorOne PL14610, with the same baseplate design and red silicone gasket.
But, compared to the Purolator, the Pentius has:
• A much thicker can
• Much more media area (from some rough measurements from the photos, I estimate 1140 cm^2 for the Pentius, vs 768 cm^2 for the POne)
• A less restrictive centre core
• A better bypass valve design (IMO, the Purolator-style bypass is restrictive)
• Similar efficiency
• Lower cost

Did you notice any difference in the bypass spring pressure between the 7317 and 3593A you cut open? I might try one of these on my Subaru, ideally whichever one has a higher bypass setting. I might just buy one and cut it open to measure it.
