This is my first post here. Both of these filters came off of the same 2016 LML Duramax. The PF2232 is the original factory filter that was used for the first OCI for this truck. The truck was bought brand new in late December 2016, the 23th IIRC. The OLM was ran to 0% for each OCI. The Mobil 1 (M1-303A) filter is a better looking filter to me, but I don't see any issues using the ACDelco filter for a full OCI. I didn't count the pleats, but the M1-303A obviously has the most pleats. The Mobil 1 filters are about $10 and the AcDelco is about $7. All of the grit on top of the filters is from cutting the filter canister open with a cutoff wheel and angle grinder.
The PF2232 was in service for 7,684 miles and 534.5 hours. OLM=0% (Oil and Filter changed on 5/27/17 with Delo 400 SDE (CK-4) 15w40 and an M1-303A)
