iOS or Android?

“What’s best” always depends on what you want to do. This is my impression of which of iOS and Android is better in different circumstances:

Lowest cost Android
Any specific single feature (best camera, dual-sim, FM radio, etc.) Android
Best build quality iOS
Easy to modify Android
Secure from other people modifying it without you knowing iOS
Smart Watch iOS
Smart Watch if you don’t like the Apple Watch Android
Virtual Reality Android
Voice control interface Android
MacOS integration iOS
Meaningful choice of web browsers Android
