G Services were never a part of android though, and android is fully functional without them if youre running a FOSS suite of apps. There are multiple options to restore GService functionality while maintaining privacy such as MicroG which is a reverse engineering of GServives to make them FOSS, and Sandboxed GServices which is literally just gservices, sandboxed, which will provide 1:1 compatibility with all your apps provided youre fine with having google code on your device.
In terms of "control" on Android, it really depends on what you mean. On Android you can still uninstall every app you want provided you have access to ADB, unlike Windows where you can't uninstall the damn built in web browser. Android also makes a lot of privacy features easier to access such as the ability to immediately turn off your location/camera/mic on the fly if you add them to your notification shade, as well as the Android 12+ feature of the "privacy bubble" that shows you if any running app is currently using location, camera or mic. There are definitely things Windows is "better" at, such as tweaking the UI/UX, but in all fairness if M$ could disallow that without breaking their legacy codebase they would.
