We use TailwindUI - combined with Django gives a really nice kickstart on new projects. Just made a Proof of Concept last two weeks for an internal business app for a new customer and did impress them easy with a working app + login + responsive nice looking layout. Used VUEjs for menu's, keyboard events and a location picker.
I've used more component-based frameworks like Bootstrap before, but I've found it's easier to have a set of utilities and build my own components on top of that.
