"Out of those claims the "language X is more precise/able to express more nuance than Y" is probably the reddest flag of them all." It seems like there are plenty of cases where some language is able to express some nuance another is not. It's just that there will be some tradeoff in return because there isn't a language that has all the details. The real problem is the implication that because some language is nominally superior in some particular dimension ("more precise", "more nuanced", "more deeply integrated into the grammar") in the vast set of dimensions languages have then it must be somehow "better", or that we can assume this relationship will be shown in all possible dimensions of comparison. But I agree it gets oversold. English can't properly express the concept of schadenfreude... except I just did, because we imported it because we liked it, and it's an English word now too.
