Rectifiers have two parameters of interest - maximum forward current - and maximum reverse voltage. A rectifier is generally chosen based on these two parameters.
Other parameters include turn-on/turn-off time, forward voltage drop, and capacitance. The importance of these and other parameters depends on the circuit design requirements.

bridge rectifier is the best rectifier.
Working the rectifier
Rectifier is used to convert alternating current to direct current.
there is no need of bulky centre tap in a bridge rectifier. TUF(transformer utilisation factor) is considerably high. output is not grounded. diodes of a bridge rectifier are readily available in market. *the PIV(peak inverse voltage) for diodes in a bridge rectifier are only halfof that for a centre tapped full wave rectifier,which is of great advantage.
In a rectifier made of just diodes, the diodes have a voltage drop, resulting in a lower DC output voltage. By introducing an Op-amp, this voltage drop can be overcome. Since there is no voltage drop caused by the diodes, the rectified signal is not changed by the rectifier, so it is called a precision rectifier.
