既然两款产品都是由同一 SDK 提供支持，为什么有人会使用 Google Analytics for Firebase 而不使用 Google Analytics（分析）4？

Google Analytics for Firebase is designed specifically for app developers, offering app-centric features and streamlining processes like deep linking. While both Google Analytics 4 (GA4) and Google Analytics for Firebase use the same underlying SDK, Firebase provides a developer-focused console and tools that integrate seamlessly with other Firebase services for app development, such as Crashlytics and A/B Testing. GA4, conversely, is a more general-purpose analytics solution for both web and app, offering a unified view but without the same depth of app-specific developer tools. The other options are incorrect because Firebase is not exclusively for Android users, its reporting capabilities are integrated into the GA4 interface, and its privacy compliance is similar to GA4.
