What is the difference b/w and use cases of GetComponentByClass and FindComponentByClass?

Have been trying to get a pointer to a UPhysicsHandleComponent from the owning Actor using: UPhysicsHandleComponent* PhysicsHandler = GetOwner()->FindComponentByClass();
which works.

What is the real difference between using the FindComponentByClass<>() function and GetComponentByClass()? Can both be used in similar use cases? If not what are the use cases?

GetComponentByClass is actually just another alias for the untemplated FindComponentByClass.

If you look at Actor.cpp, you’ll find the following:

UActorComponent* AActor::GetComponentByClass(TSubclassOf<UActorComponent> ComponentClass) const
{
	return FindComponentByClass(ComponentClass);
}

I have witnessed this a lot in the source code, is there a reason why they would do that?
