ME: Best: Tungsten. It's just good all around. Worst: Explosive. Isen't as powerfull as one might think and it overheats the weapon to fast.

ME2: Best: Armor Percing. Same reason as Tungsten. Worst: Warp. Even do it works against many forms of defenses it is just to weak to make an real diffrence.

ME3: Same as ME2.
