I tried to do some comparison and it seems the best for some reasons

The Physical Warfare is just a time exclusive bonus; Strategy Guides (printed) usually never work for multiplayer games; the unique dog tags may be exclusive but you can only wear 1 at the time (or you would want to) but the SPECACT skins are exclusive and you can have them all in one match (the good soldier changes to his environment; hence changing kits)
