"Educated Collector" no, if you were an "educated collector" you would already know that 1 company is a hack and the other is infallible. Name 1 time CGC has made a mistake, times up, you can't (because I didn't let you). But in all honesty, if the book presents as graded it sells for FMV plastic grading company aside. I have bought and sold quite a few of both, and I can honestly say that I haven't had any issues since the "new case" debacle awhile back where I had to keep sending books back, had to have books pressed to try and retain grade, etc.
Both companies will continue to have ups and downs and as time goes on there will be (2) major grading companies. And I will continue to use CGC at some point in time, most likely once I feel their grading is consistent again.
