1. Performance: Framework7 is known for its high performance as it provides native-like experiences to users, while PhoneGap relies on a WebView to render the UI, which can lead to slower performance. On the other hand, React Native offers a high performance by directly compiling JavaScript code to native code, resulting in faster execution.

2. Code Reusability: React Native allows for a high degree of code reusability between different platforms, enabling developers to write a single codebase that runs on both iOS and Android. In contrast, Framework7 primarily focuses on creating web applications, and PhoneGap allows for some code sharing but does not offer the same level of consistency as React Native.

3. Native Components: React Native provides access to native components through its JavaScript API, enabling developers to integrate platform-specific features seamlessly. In comparison, Framework7 and PhoneGap utilize plugins to access native features, which may not always provide the same level of performance or functionality as React Native's approach.

4. Community Support and Ecosystem: React Native has a large and active community that continuously contributes to the platform's development, providing extensive documentation, libraries, and tools for developers. In contrast, Framework7 and PhoneGap have smaller communities and ecosystems, which may limit the resources available for developers seeking assistance or additional functionalities.

In Summary, React Native offers superior performance, code reusability, access to native components, and a robust community compared to Framework7 and PhoneGap.
