The difference is programmatic cad can have composable, repeatable, and automatable operations. What if you have a thousand corners to fillet, in some kind of gradient, so each is a little different than the last? You won't be clicking and menu-ing your way out of that. What if you want to do transforms on models as part of a process, like read a pile of models and do something to each? Programmatic. And then you can pass that process to another transform doing something else. etc. In a programmatic cad system, it's just a few lines of code.
