I think comparisons of languages in terms of their beauty or elegance
are subjective matters.
I think Esperanto is still sufficiently European that it presents
problems that learning any simplified European language would present
to speakers of languages outside the European orbit. In that sense
I don't think it can pretend to be any more global than other languages
that make similar pretensions to be languages for the whole world.
There has been a Chinese critic of Esperanto contending with Esperantists
for some time now at sci.lang that the language is not that easy for
Chinese. He knows Esperanto and English. In some respects, I think
this represents some pride he may have in Chinese and an inclination
to resist languages of European origin that make global claims for
their use, which we may expect to encounter increasingly as China's
economy grows and China and its civilization has a greater influence
in the world.
