I've used Tailwind, Bootstrap, and most recently I built a project with Vuetify. I'm looking forward when I have time to completely re-write the entire app with clean SCSS sheets, organized in a meaningful manner, dropping the metric ton of useless divs of `col` and `row` and everything else, and ending up with a clean, more manageable, more easily understandable app structure.

For those that know how to organize their CSS (or better SCSS), using these frameworks is not a benefit, and while the speed is quick at first, it ends up being difficult to edit later as you try to slide things around, only to break other things, create weird spacing issues between elements that are never perfectly responsive, etc.

Oh, and that's not to mention how completely fucked the components' logic is in Vuetify. There are things I do all the time in other apps which are IMPOSSIBLE with Vuetify because of the ridiculous structures they've imposed.

The best app is one which is tailored for its specific purpose. Use only the packages you need, write your CSS without the need for treeshaking (since every class is used!) and also greatly reduce your local compile and build times.
