True, but the question of which is "better" also involves which is
more portable to currently deployed systems IMO, and I do not have a
feel for whether aligned_alloc is actually out there and usable on a
wide variety of systems. C11 is only a couple of years old and only in
the last few years have we seen a widespread push to use C99 idioms
and even now there are projects that avoid C99.
