I'm currently looking at Oblivion's Game of the Year Deluxe Edition on Direct 2 Drive, Impulse, and STEAM, and noticed that they're all priced the same. I feel retarded now that I remember that I traded in my boxed copy through Goozex a few months ago. If given the choice among all three of these services, which do you choose and why?

I personally like to buy through Impulse, because they are a Michigan-based company (located about 20 minutes from my house) and because they're the underdogs in the digital download world.
