Comments on the machining qualities, UV resistance, and overall strength of
these would be greatly appreciated.

I have limited experience in the others but like Delrin (Acetal). It
is very durable, easy to work with (for an amateur like me), and is
easy to get a good finish on in a machine. It is also available in
versions with very good UV resistibility, much better than Nylon.
