I'm not sure what "Ian" signifies in your question. Perhaps you intended to type "is"? If so, why do you think one language is "better" than another? What would that even mean? People who speak Ibo understand reality in the way their language permits; same for Tagalog, German, Amharic, Hindi, Urdu, Spanish, French, Dutch, Russian, Gaelic, Czech, Berber, Oromo, Yoruba, any language. Great literature exists in all these languages, and expressiveness is not the property of one set of phonemes any more than another.
