On the whole I would say the English version is better. In general articles about China tend to be pretty good (modern and ancient history, people as you pointed out) and can be richer than their English equivalents. I actually haven't found the linguistics articles about Sinitic languages to be all that helpful. My impression is that they usually have less information than their English equivalents and often have sections translated from their English counterparts (I'm fairly sure the translation is in that direction because the English is more detailed than the Chinese and the original sources are usually in English), but I suppose YMMV.

However as you get into the various sciences, the quality and coverage of articles drops off very quickly.

I also find that the tone of the articles can also veer off a little bit from the usual encyclopedia-detached tone of Wikipedia (at least somewhat more so than the English version)

I still prefer it to Baidu's online encyclopedia, but it's not as excellent as the English version.
