Hi-
For GI-Joe I would use Savage Worlds. Why ? Because I assume the players will be playing as Gi-Joes so the detail of the chosen system should be focused on skilled but normal men. Mutants and Masterminds (the other game I would consider for this setting) is focused on super powers. In Savage Worlds, the details of the system are focused upon skilled yet normal men so there is more "space" to differentiate the characters.
Now you might ask what about Spycraft ? D20 Modern ? I would respond that as a Gi Joe I want to fight in vehicles, with automatic weapons, with 30 or 40 opponents and allies on the table at the same time...and I want to finish several such combats in the the course of one evening ... so I would pick Savage Worlds which is designed for exactly these sorts of situations.
