npx prettierMy fear with Biome is missing out on type-aware lints, but I know Oxlint has had some success integrating the new Go typescript compiler, so maybe that will work out for Biome as well.
Arguably, code formatters should be configurable, to get a format for your code that you want. Unfortunately, prettier isn't one, and it is a form of regression in many communities at the cost of choice pruning.
It might be great for a CI pipeline for constraining how code should look (use prettier, dumbass!), but it isn't great for actually formatting code, as it just makes the code "prettier".
Even though prettier has defaults, but they can be modified to quite some extent to suit your projects needs: https://prettier.io/docs/options
