I haven't used pybind yet, so I can't compare the two unfortunately. From how I understand the docs it seems you would have to write the interface definitions in C++ and the compiler would generate the bindings for you, which sounds like a nice approach that could be a bit more cumbersome though as (again, in my understanding) forces you to write and adapt all bindings by hand.
