The grading standards that the two companies use right now is just different. An SGC 60 is going to be a PSA 3.5 or 4 in most cases.
People pay more for the same grade in a PSA holder, but it's not just because of the registry or anything else. An average SGC 60 is going to be a much weaker than the average PSA 5 (under current grading standards).
In my opinion it doesn't make one company better than the other, and doesn't mean one of them is making mistakes. They just use slightly different grading scales.
