Chesterton’s fence should apply here I think. Sleek isn’t what matters in most domains, fast is more important but suffers from what definition of fast and how you measure it, in my experience working on a lot of enterprise systems what users really want is software that fits the domain and is predictable and consistent. Everything else is gravy.
