I think for your engine Purolator suggests the PureOne PL14460 or Classic L14460. Both have a relief valve pressure rated 20-25PSI. The only downside to this filter is that there is no ADBV. The OEM does.
If you're not racing your Subaru, want it to last a good long time, do normal OCIs of around every 3,750 miles, and aren't "tricking" out your engine with a bunch of weird enchancements that it was never engineered for then the Subaru OEM oil filter will do you well.
