From my point of view: A static inline function is a much nicer modern code style than a C preprocessor macro.
It's also slower to compile, given that function inlining happens at a much later point in the compiler pipeline than macro expansion. The C compiler won't even get to see macros in fact, whereas whether to inline a function or not is a dedicated decision during the optimisation phase based on metrics collected in earlier stages. For something as ubiquitous as Py_INCREF/Py_DECREF, it might even be visible in the compilation times.
Have you measured this? I had the opposite intuition, that macros on average will be slower to compile because they increase the amount of code that the frontend has to process. But I've never checked...
