The output voltage from a centre tapped full wave rectifier is half of what you would get if you use a bridge rectifier. So with a centre tapped full wave rectifier, you would need a transformer with double the number of secondary turns to get the same output voltage as you would get from a bridge, and because current only flows through half the secondary winding at one time to get the same current as you would with a bridge, you would need a thicker coil in the transformer (the current rating of the transformer would have to be approx 1.41 times larger compared to the bridge circuit.) So it appears that everything points to the bridge recifier in terms of efficiency (more energy will be dissipated in the centre tapped full wave rectifier transformer), and physical size but the full wave rectifier uses less semiconductor material

The transformer is simpler in construction and weight, it's also cheaper when a 4 diode bridge is used. On the down side, the diode voltage drop is doubled in a 4 diode bridge when compared to the 2 diode used in the centre tap transformer model.
