The larger the number, the greater the deformation of the waveform, so bigger is not better, at least when talking about the output of an amp.

    If the amplifier has a high slew rate the deformation of the square wave will be less, because the sloping rise and fall of the reproduced waveform will be steeper. That is the voltage can rise to the maximum required level in a shorter period of time. The slew rate is precisely a measure of how fast the output voltage can follow that of the input waveform. It is a measure of how steep the rising and falling parts of the waveform can be. An ideal, perfect, amplifier would have an infinite slew rate, so that a square wave would be reproduced without any distortion; the rising and falling parts of it would be vertical.

    Hence the higher the slew rate value, the better.
