It comes down to your set up mostly. If for what ever reason someone doesn't at least have a decent reload then the capacity/reload speed can be cumbersome, but with a decent reload speed it's an irrelevant factor. mixmaster's pierce is low & its DPS, compared to sub-light, is lower; again, though it depends on your set up. Personally, regarless of my setup, I'll take the sub-light over mixmaster always. Mixmaser is good though.
