FedEx for some reason is about twice as expensive as DHL. I don't think the service is any better.
I have been living here for 3 years. I have a mailbox service in the US (USA Box - usabox.com, I really recommend it) which collects my mail for me there and once a month I have it sent to me. They use DHL to send my mail and in approximately 35 shipments I have only had a single problem in all that time (more below). I have ALWAYS received my mail within 2-3 days from the day I tell the service to ship it. I have been in temporary apartments, a long term lease apartment and now a house, all with various issues in addressing (I have no actual street address where I currently live for example - it is a description).
I have sent documents to the States 5 times over the three years, including some sensitive court papers. No problem whatsoever with receiving that.
DHL has a truly last generation package tracking system (I'm sure FedEx probably does too, but I don't use FedEx). I know every hour or so sometimes where a package is. The one problem I had with DHL was something local. My address starts with "Patricias Argentinas y Mar Del Plata Golf Club...". Some smart guy here in Argentina decided to send the package to Mar Del Plata the city, even though the rest of my address had "Garin, Gran Buenos Aires" and the correct postal code! When the package didn't show up after three days, I looked on DHLs website, saw where it had been delivered, and saw that the status was something like "attempting to resolve address." I called DHL in the States and in 5 minutes they had everything straightened out and I had my package the next day.
USPS is good within the States, but it will come through Correo Argentina, I believe, on this end. I have heard both good and bad with Correo Argentina from a number of different sources. I've actually heard more good stories than bad and therefore I can't say not to use it.
But for me, for a one-time use (or even a couple of times), I can't see any reason not to remove all complications that one can to ensure that something important like visa papers makes it to the right place as quick as possible. I'd send via DHL on both ends.
