Windows Subsystem for Android™️ (WSA) enables your Windows 11 device to run Android applications.
Even though optimization techniques such as Intel HAXM are available, there is a marginal performance tradeoff when using the Android Emulator.
The Subsystem has been designed to function as an integral OS component, providing superior performance compared to the Android Emulator.
From my perspective, the only drawback of using WSA is the lack of support for Google Play Services (as it works with Amazon Appstore). So any apps that rely on those services, WSA might not be the best fit. So continue to use the Android Emulator or the Physical device.
