This is subjective, but as a photographer, the camera does color balance and skin smoothing better.

Once you are in the ecosystem AirPlay is a much better experience than Chromecast (I’ve spent $1000s on both, so I can compare)

Copy paste between Apple devices is automatic. My iPad can serve as a second monitor for my MacBook automatically.

You can run your apps on your computer without any fiddling. (Can be done with Android. I want to be fair in my list for you.)

Honestly, many of the benefits are greatest when you’re in the ecosystem. I own two MacBook pros, and iMac, and two iPad pros, oh and an Apple TV. For me, the iPhone made a ton of sense. My files are everywhere. My apps are everywhere. Everything is everywhere, automatically, with no effort.

Android *can* do many of these things. But it takes 0 effort Apple, and I spend enough time fiddling around with other things. I opted for convenience in this case, and I’ve been happy with the overall experience.
