With your modeling skills, you'd only need it as a time saving short cut to what you're already quite capable of in my opinion. It doesn't make "Thick" cloth except via material displacement. You'd still need to do as you've surmised and save out an OBJ and edit it from there. Do you really need that short cut? That's something only you can decide. For the non-modelor in myself, I love it for what it can do not what it can't.
