Bruno, in this case, familiarity is not a stylistic issue so much as fluency with the syntax of the language.

You wouldn’t hire somebody unfamiliar with English grammar and syntax to write your technical documentation.

The assertion that there is no “objectively better” way is wrong. There is, and it will be provable.

When more people are familiar and we have enough data, there will be bug density and productivity measures that we can objectively compare.

My money is on the developers who are fluent with the language.
