Mass Air flow uses the amount of incoming air to regulate how much fuel the engine needs. Speed density uses the manifold air pressure, then looks in the computer for the amount of fuel to use. The MAF system doesn't rely on a set of fixed parameters in the computer like the speed density does. If you have more airflow than the highest parameter in a speed density setup, the computer doesn't know how to react. Therefore the engine runs like crap in a worst case scenario. Mass air will adapt to changes made to the engine better. This means it will milk more power out of every modification.

Short answer...
Mass Air - The computer uses a sensor to measure the MASS of the AIR to measure the the amount of air coming into the engine.
Speed Density - The comptuer uses a sensor to measure the pressure of the air in the intake manifold to measure the the amount of air coming into the engine.
