Out of the big 3 authenticators PSA, BGS and JSA who is generally the most accurate.  I ask because I'm in the process of buying a autograph that has been previously authenticated but a quick opinion from Beckett says they are both fake.  I don't know who to trust.  One is authenticated by PSA and one is from REAL Roger Epperson but Beckett says they are both fake.  So who do you think is wrong?  Here are the 2 autos in question.
