it's better ignore which parts of the API will be used frequently or rarely. Better think only at how easy it is to remember each item.
Even if that's the criterion, I find it easier to remember "use _GL_NORETURN for most noreturn cases, and use _GL_ATTRIBUTE_NORETURN for when you want just the noreturn attribute" than to remember "use _GL_NORETURN_FUNC for most noreturn cases, and use _GL_NORETURN_FUNCPTR for when you want just the noreturn attribute". Partly, I suspect, this is because _GL_ATTRIBUTE_NORETURN follows the naming convention that _GL_ATTRIBUTE_MALLOC etc. already use.
