What should I "re-get"?

mass effect, or halo 3....I have Army of two, and am trading it to a guy for mass effect and viva pinata, is this good, or should i try and trade it for halo 3. I have previoulsy owned both of these games,and thought they were both good, just looking for some help from the crowd. I currently have: Gears, Cod4, forza 2
