As a long-time MUI user myself, I had the same "revelation" about Tailwind recently. Before MUI, I worked at a couple startups where we came up with our CSS franken-framework with homegrown utility classes.
It's just easier to do fast proto-typing with various Tailwind classes, and then refactor common sets of HTML tags with tailwind classes, they become reusable React (or Svelte) components.
