We use ESLint because we like to remove the general thinking-overhead when writing software. ESLint offers many presets, while also providing users with a lot of customization features. We use ESLint in conjunction with the javascript "standard" configuration (and for our vueJS-projects the "recommended" settings).

The other option we considered was JSHint, but we scrapped that, as forward-compatibility is essential for us and ESLint is more fast-paced in its development and supports ESnext natively.
