Every time I have to click twice instead of once during my once every ~3 years VSCode setup process, I think to myself "If only I could replace Prettier and ESLint with one tool, I could save about 5 minutes during my lifetime."
Replacing prettier and eslint in my projects will typically remove about 5 dependencies. Sometimes up to 10 if you have a lot of specific plugins.
Another amazing benefit is that because Biome is a compiled binary, it can run _without npm install_ which means you can use it in your CI for linting before running any expensive build steps.
Those things save me time.
