Assembler CSS doesn't look very good and I wouldn't use it ... but I have come to absolutely love utility CSS through Tailwind. Tailwind's documentation does a good job explaining why: https://tailwindcss.com/docs/utility-first

It's really not very similar to writing inline styles, nor is it about saving keystrokes. It's about very quickly and confidently translating a design in your mocks (or your head) into working CSS which draws from a finite design system that you control.

It't not something I'd use on mywebsite.com/about.html but it pairs really nicely with modern JS frameworks which allow you to create custom elements with scoped styles.
