Behaviors/Handlers/Triggers/VisualState use cases

I've been reading through the .Net MAUI docs on docs.microsoft.com and am having difficulty making the distinction between use cases for Behaviors, Handlers, Triggers/VisualState.

It seems they all accomplish the same thing, particularly Behaviors and Handlers. In fact, the documentation pretty much uses the same example (Entry control customization - validity check, background color, etc.)

So what are the use cases for each? When is one technique better than the other?

Thank you.
Mike
