I’ve used both for years. iPhone is simply the better device compared to any Android phone I’ve tried, including Pixel and other high end phones.
iOS is a better OS for me. I’m a software eng, and so I’m able to do all sorts of things to androids, and some things to iOS, but at the end of the day I want my phone to work and that’s it. I don’t tinker in my free time because I tinker all day at work.
As others have mentioned, the Apple ecosystem is pretty fantastic.
Finally, I’d rather buy hardware/software from a hardware/software company than an advertising company.
