Alias lamda argument vs Type template argument

[Freddy via Digitalmars-d-learn]

There are two these different ways to pass functions as template 
arguments. Which is preferred?
---
void funcA(alias calle)()
{
     calle();
}

void funcB(T)(T calle)
{
     calle();
}

void main()
{
     funcA!(() => 0);
     funcB(() => 0);
}
