Accuracy in delivering meaning isn't the only measure as long as the accuracy is acceptable.
Though English can be clumsy with accuracy at times, I do think English is a little better in this respect in general while Chinese is good enough. Still, this is only a very general statement. A friend of mine with English as his main language and poorly trained in Chinese comments that Chinese is a better language in conveying Buddhist ideas. He thinks English is unnecessarily clumsy for this purpose. So he reads Buddhist texts in Chinese instead.
As well, a language maps reality from a variety of approaches. One is better off with some approaches and less so with some others. The so called"scientific" quality of a language only implements one of those approaches.
In conclusion, all we need is a mature language.
Both Chinese and English are mature languages.
