I think that the main issue here is to define what is better. For example. If I am creating a new startup and have money for only two months - "better" in this case is rushed out code (whatever that means). I.e. the software have no future in any case, if it is not delivered on time. However, if I develop radiology machine. Better in this case is very exact state machine description, otherwise I can kill patients. In those author specific case, we are talking about business system in the enterprise. The "better" here is how fast and easy I can change those system, since I get new requirements every week.
