I have Android and iOS. There's some things both do better than the other. However iOS is the best when it comes to support, UI, and overall ecosystem.

For example Gboard on Android is unmatched. I also prefer Amethyst over other Nostr apps. The rest of the apps look like early 2000s flash apps.

iOS has better apps. Seamless syncing between other apple devices. Files integration for a lot of apps. And lastly Safari has a ton of really useful extensions.
