Closing the thread is not called for - and even if you are the only person who holds your opinion, it is a legitimate topic and certainly given me insight into how the rest of the world views the various dubs of the different animes.
I enjoy your contributions to ABO, and have one more comment on this topic . . . You don't really hear anyone call Atom "Astro Boy" in the 2003 dub either. They call him "Astro" more than anything else. "Astro Boy" is actually an awkward name - more of an adjective than a real "name."
So, in the end, Atom and Uran's original Japanese names really do function best as their names, don't they?
