Joe_G.I'll bite as well (from the perspective of 19th century sets). . .
SGC 8.5 The best, but no one gets it right all the time, even SGC has room to improve.
PSA 4.5 PSA just doesn't understand OJ & GQ, two of my favorite sets. With greater frequency than the others, they mis-label, grade altered, and don't even try to hide how clueless they are. Case in point, the N173 Connor on eBay (not the GQ mistake that lists a small GQ as large). PSA decided to list the pose which is a cool idea but "BATTING OUTDOOR SCENE"??, come on! Connor has 3 batting poses, all shot in a studio indoors. The correct pose description (Cartophilic listing) would be "Bat at ready, L/profile". There is a good reason why a much smaller SGC has graded more than twice as many OJs than PSA. Unless something drastically changes to either SGC or PSA, that gap will only grow.
GAI 6.0 A host of issues themselves but certainly better than PSA if for no other reason that their cards don't slip around.
BVG ?.? I don't have enough experience with BVG to fairly grade them.
