Spoken language, Russian. Just highly versatile and allows for culture, scientific notation and everyday use, and adaptable to emotion change (as in, you could say the same statement angrily, matter-of-factly and romantically without sounding awkward in the slightest).
Written language, it'd be a ***** for everyone to learn Cryllic. Most Russian-Americans don't know how to read or write. Russia does have a 99.9% literacy rate, though, so I guess it'd be possible if you learned it since birth. In the meantime, we could still use the Latin alphabet. Something about written Chinese (and before anyone thinks of it, Mando and Canto have no changes in the written language) just sticks out to me. I don't know why, but I have a feeling it's a superior written language.
You're kidding, right? Mandarin and Cantonese have many changes in the written language. Why? The writing system was invented for the predecessor to Mandarin (Well at least the northern dialects [官話]), not Cantonese (A Yue language [粵語]). Sure, they started off in Old Chinese, but the divergence into Middle Chinese changed the usage of characters, mainly because of differences in pronunciation.
Also, the characters are more superior when they are traditional/complex characters (the ones used in Taiwan and Hong Kong), as opposed to the People's Republic of China. In general, this is because the characters in China have been simplified with sometimes little regard to meaning. In Taiwan and Hong Kong, characters still retain their meaning and contextual clues (the little bits that make up many words reveal meaning, where some don't exist anymore in simplified Chinese). It may be easier to memorize the smaller characters in China, but if you want meaning, then you'll have to go with traditional Chinese.
OT: Anyway, it's a difficult language family, Chinese, so I wouldn't see it as being good for a world language.
I chose French, mainly because the language is fairly expressive and at least pleasing to the ear. Also, a lot of the vocabulary remains the same from my native language, so it's not been that hard to learn to at least
read it. Now, speaking it is a whole 'nother matter...eh, not too bad.
