The amount of styles as references is good, sometimes i tweak them into my own.
AAMS is very very very usefull for me, it does more then mastering.
But i take it will not be everyones tool, still afther a while AAMS software is easy.
It first it can mislead you into hardness or strange tool.
As the manual reads, just try a few single button masterings first.
And later on you get the grips more, you will find out this can be a lifesaver.
