Corey: In all honesty, I trust my opinion of a card more than either PSAs or SGCs (as I’m sure you do) and do not rely on either to tell me if a card is good. My reasons for slabbing a card would be protection and/or resale value and with those criteria I think PSA is the clear winner.
As for knowledge, I think SGC is worse at detecting trimming, and they both miss more other things than they should.
