This is a false dichotomy IMHO. "Hacky code" is most often a result of those responsible for delivery having gaps in their understanding of the product need.

This is a false dichotomy IMHO. "Hacky code" is most often a result of those responsible for delivery having gaps in their understanding of the product need. When engineers have a deep understanding of what is needed, there is rarely a need for hacks. Of course, the obvious exception to this is when libraries and/or external services mandate them.
