You can back up your iPhone completely to a computer and restore it on a new iPhone. Android has nothing like that.

Day one updates. No waiting. Only the Pixel is like this.

Accessory ecosystem is really good. The iPhone is the default for most things in design and due to the limited number of models, most things fit around an iPhone better.

If you have a Mac or iPad, iMessage on those is nice and various cross device features are also nice.

Apple isn’t an advertising company, so they at least pretend to care about keeping your data secure. And more recently they’ve enabled features where if you don’t safeguard your passphrase, you will not get back into your account.
