Semantic UI vs. Material UI vs. Gumby

We haven't yet, but we would like to integrate into our Web App.

CSS components (design)

I'm using MUI to build out the admin portion of the site under Firebase authentication.

Material UI provides Cloudcraft.co with a clean, professional looking and very easy to use set of UI components build with React.

The styling system in particular is very nice to work with, and allows you to easily add your own brand's look and feel throughout the UI.

Modern UI framework

Ambar UI is based on Material UI components
