Today, it is more about maintaining your suite of apps, the Cloud with all your data, the little blue bubbles in your group chats, and a host of other issues that are more a priority for choosing one platform over another, for most people. If I were to switch to Android now, it would be a huge PIA considering the 10+ years of platform integration and thousands of dollars of app purchases, iCloud, etc, that has made up a significant part of my digital life. I'm sure it would be similar for people going in reverse. Apple knows this, hence why services have become an essential part of their business.
It’s not a “it’s not iOS” thing, either. There are certain desktop Linux setups for example that don’t bother me nearly as much. It’s just Android that feels “wrong”.
If only the entire front end of Android were interchangeable like Linux DEs are.
