I would pick Beckett as a secong choice unless I have a EX front card and a bit of damage on the back then PSA so that way I can get a really high grade for a really low grade card. SGC is #1 for me and I don't buy many beckett cards because I don't see many in my collecting interest to buy. They are very consistant from what I have seen and market does normally command close to Average so this is good.
Jeff the BVG Mantle hands down. Then cross to PSA for a 9 and off to auction
