I answer for the two libraries I'm concerned with.

This is now an integral part of the ocaml distribution, available on
both Unix and Windows (in ocaml 3.00). The interface should be stable
in the future, making it a good choice if portability and
maintainability matter.

Beta does mainly mean that it may undergo API changes in the future.
It is already good enough for writing applications. The next version
will also support Windows.
This is a good choice if appearance matters, and you are ready to
eventually suffer a bit with API changes.
