Material UI provides best libraries for creating user friendly interface in the web-development.

I like how simple and clean the components are. The code is also pretty clean, easy to understand, and easy to implement. They also have different icons styles for all my needs and are pretty standard so that users are able to understand them as well. The material colors are also easy to use in how they label the colors. The colors are also designed to pair well with each other. Also, if needed you can always edit the components/code to customize the design to your needs. For example, it's really easy to change the corners of any component to suit your style/brand. The documentation online is also extremely helpful and provides additional resources you might need when building UI.
