Well I can tell you SOME of the unlocks are superior. Of course it's my opinion and my aiming ability. The Spec Ops unlock is worthless, The Engineer unlock is worthless, Support is a little better accuracy but less dmg-- so again worthless ( the PKM is better actually), so the only two that are worth anything is the Medic and Assault. The F2000 is wonderful, you can actually snipe with it, but too bad it's only 32 dmg, but does have a GL, and the Medic is basically the original unlock for Spec Ops. Again just my opinion. Take it for what it's worth, because I made 2 unlock mistakes.
