Which one to keep?
 

I recently acquired the card on the right as an upgrade to the one on the left, but now that they are both in hand I’m no so sure it was an upgrade. The PSA 2 has a spot of paper loss on the back but features much better color and sharper corners.

Which would you keep?

I'd either keep the 4, or if you don't like it look for another one. I'd feel otherwise if the paper loss on the 2 didn't involve an area of text.

Personally, I am ok with back issues if the front is presentable. I would keep the 2 and keep an eye to the future for upgrading

graded soccer cards
 

PSA is notoriously poor in grading soccer (which is why I never send to them).

I have a folder full of psa erroneously slabbed cards.

They are money grabbers as far as I'm concerned. I've had positive talks with other grading companies at the National Sports Collectors Convention in Cleveland

While I understand that grading is subjective, I find psa baseball cards that look run over by trucks graded 5 while near mint soccer cards pull 2 or 3.

That's just bias or ignorance.
