difference between low-reflecting boundary and PML

I am trying to simulate vibration (acoustic) wave on the surface of a substrate. And I want to reduce the reflection, for which I tried two methods: applying low-reflecting boundary condition or building perfectly matched layer in the model. However the results given by the two different methods are quite different.
Can any one tell the difference between the two? Besides, when I apply perfectly matched layers, does the thickness of the layer matter?
Thank you!
