I've used nom to implement a Turtle parser. The result was fast (it runs the test suite in 50ms) and the code is pretty readable. Certainly much more readable then if I'd used a homegrown set of functions. I've documented the specification grammar rules next to the nom rules. They match up well. Nom can be tricky to debug, but Rust can host tests in the same file as the code, so debugging by writing new tests is convenient. The syntax takes some getting used to. The hardest part for me was learning to order the grammar alternatives correctly. The order matters for performance and correctness.
