IMO
Beckett doesn't command prices in pre war because pre war collectors typically are seasoned collectors and know that Beckett is gracious with their vintage grading.

KSA is a legit Canadian company. Good in hockey BVG like in baseball.

CSA with the blue insert w/o a detailed flip is adequate. Everything else is rubbish.

SCD with red flip is good, blue flip is worthless.

SGC is great with a crappy registry.

PSA is all about $$$$. Profit margin rules, and VIP customers get preferential service (grades). Awesome registry with inconsistent grading.

GAI for post war isn't that bad. A notch above Beckett.
