I prefer iOS because I spend most of my time in apps.
iOS apps tend to be more stable and higher quality.
iOS Developers are incentivized to make a quality apps, thus get more long term support. iOS devs tend to make more money because of this.
I dont spend my time on my home screen or launcher, so the customization benefits are not important to me. I want a longer supported OS where I dont have to worry about OS issues, or security out-of-date stuff. Android OEMs do not updating their OS often, and their fragmentation is currently unstable. Google's own pixel/nexus phones dont even get long term support to the latest OS.
