Really lock down privacy if you want:
1. Don't send location or app install data anywhere.
2. Route phone calls and SMSes through encrypted communication services automatically.
3. Develop and run applications without telling anybody.
4. Ublock Origin in the browser and adblocking across all apps (not just browsers).
Most people care about usefulness instead of privacy, and Android beats iOS there as well:
1. Install apps from the Play Store using your desktop web browser.
2. Start Android Auto on your phone when connecting to the car's Bluetooth automatically and use it directly on the phone without buying a separate headend for the car.
3. Upload photos automatically to photo services in the background.
4. Route outgoing calls automatically through Google Voice, so when people call back, you get transcripted voicemails for free.
5. Multiple user accounts, so you can set up a restricted kids account on your phone and hand it to them for entertainment in a pinch.
6. Install apps from other app stores, like Amazon's, that also run deals for free apps.
7. Game console and calculator emulators.
8. Browsers that aren't years behind in standards support, so you get installable PWAs for Twitter, WebRTC, etc.; and you don't have to put up with bugs for years until the sole renderer vendor fixes them (e.g., iFrame scrolling on iOS).
