Brushless stator - Silicon Steel vs Supermalloy?

It seems like the standard for brushless motor stators is Silicon Steel, while doing some research I came across a reference to Supermalloy and how it amplifies a magnetic field 25x better/stronger than Silicon Steel. If this is correct, can I assume Supermalloy would make a better brushless motor stator and if so what are the tradeoffs, example is Supermalloy considerably more expensive, harder to work with, etc.

If Supermalloy is expensive what are the alternatives, e.g. different/better variations of Silicon Steel?
