I ran the PF47 equivalent Microguard out to 6000mi during my last OCI. The Microguard wasn't my first choice. I had a Purolator, had already drained the oil, and removed the old filter.....
.... and dropped the Purolator on the concrete denting the bottom of the can in.
O'Rielly's was the closest shop and I needed to finish the job in a hurry so I picked up the MG since they were out of ACDelcos.
They are slightly different than Frams branded filters in that the media in the MG is rated at 94% SPE instead of 95% (same micron rating).
For the money however ($1.50 difference) I'd just go with the ACDelco or even the NAPA.
