Greg EcklundFavoritism in submission seems to be much more of a problem for PSA than SGC...I don't think you will have a problem with sending it in yourself.
That said, I would definitely wait for a big show in your area where SGC will be present in order to submit the card personally. The post office has always been super reliable for me with only one or two exceptions, but I wouldn't want to trust a card like that to any carrier, be it USPS, UPS, or FedEx. Whenever I have a card that is very special to me, I wait for shows like SportsFest (I live in the Chicago suburbs) in order to submit in person.
