What each one is
Evergreen
Evergreen is a set of ready-made React user interface components, such as buttons, that developers can drop into web applications. It is built on a styling base called ui-box and includes a theming layer and server-side rendering support. Teams use it to build consistent web product interfaces without designing every component from scratch.
Radix Primitives
Radix Primitives is a collection of low-level user interface components, such as building blocks for menus, dialogs and similar controls. The README describes a focus on accessibility, customization and developer experience. Teams can use them as the base layer of a design system or adopt them one at a time.

Strengths
Evergreen
- Components work out of the box with sensible defaults
- Built on a composable primitive, so components can be extended
- Includes documentation, theming docs, and a Next.js example
Radix Primitives
- Stated focus on accessibility, customization and developer experience
- Can be adopted incrementally rather than all at once
- Open source under the MIT License with a large community following (about 19,400 stars)
Not ideal for
Evergreen
- People who are not writing React code, since the components are React-specific
- Projects needing a framework other than React, such as Vue or Angular
- Teams looking for a long-term stable API without checking the v7 migration guide first, since the README points to a major version migration
Radix Primitives
- People who want ready-made, styled components out of the box, since the README describes these as low-level primitives
- Non-developers looking for a finished website or app builder
- Projects that do not use React, since the topics and description point to React
Trade-offs
Evergreen
- The README shows the older ReactDOM.render example, so check current docs for your React version
- Requires moving through a v7 migration guide if upgrading from earlier versions
- Last-known README copyright is 2021, so verify the project's current status before adopting
Radix Primitives
- Low-level by design, so you must add your own styling and layout work
- The README is short and points to external docs for component details
- No formal release is listed, so you need to check the changelog for versioning
