That is a most interesting question. Here in Thailand I interpret their differences, perhaps incorrectly, as residential meaning a way with houses on it, while an unclassified highway is one step below a tertiary and therefore one step above a residential. It does not have many houses (residences) and is often a connector between minor towns or villages. Which is more important? In my opinion, an unclassified highway would offer faster transit times than a residential so I'm surprised to learn that routers rate them the same.
It's a tricky distinction. I hope this thread will help clarify that distinction.
