There's an Android and iOS version of pretty much every app out there, but iOS apps still generally feel like they're better optimized and designed than their Android counterparts.
Apple devices like the iPhone, Apple Watch, AirPods, and Mac computers also work flawlessly with each other. I've found features like AirDrop between an iPhone and Mac computer to be genuinely useful, as it lets me transfer photos and videos seamlessly between an iPhone and my MacBook Pro. And iMessage, which you can use on a Mac and iPhone, is still one of the main features holding iPhone users back from switching to Android.
Meanwhile, the integration between Pixel phones and Chromebooks isn't nearly as comprehensive. Plus, Chromebooks aren't for everyone, as they run the good-but-limited Chrome OS operating system that only runs the Chrome web browser, Android mobile apps, and a sparse list of full apps.
Then there's the physical presence that Apple has with its stores where you can get your iPhone X – and any other Apple product – serviced if anything goes wrong. Having been an owner of both iPhone and Pixel phones, I can attest that there's a much greater sense of support with iPhone than there is with Google's Pixel. Google has pop-up stores in New York and Los Angeles, but that leaves a large chunk of the country without a location. Plus, Google's pop-up stores are designed to showcase Google's own products rather than provide service. To get your Pixel 2 devices fixed, you need to bring or send it to Google's repair partner, uBreakIFix, which is fine, but it's not a complete "experience" like it is with Apple products.
