v10.10.0(about 1 year ago)
Both libraries have good performance, but Aphrodite is known for its highly optimized runtime and efficient style caching mechanism. JSS also performs well, but it may have a slightly higher runtime overhead due to its dynamic nature.
Aphrodite provides a simple and intuitive API for defining and managing styles. It also offers support for CSS-like features such as media queries and pseudo-classes. JSS, on the other hand, provides a more powerful and flexible API with advanced features like theming, plugins, and dynamic styles.
Community and Documentation
Both libraries have active communities and good documentation. Aphrodite has been around for longer, so it has a larger community and more resources available. JSS, however, has a growing community and its documentation is comprehensive and well-maintained.
