I agree that the apps on Android are not as high quality as their iOS counterparts in a lot of cases. I'm guessing a lot of these were ported from a cross-platform codebase such as Xamarian and there simply wasn't as much QA on the Android versions. Not sure, but I've definitely seen more issues on Android apps than I ever did on iOS.
The lack of iPhone options to integrate iPhone with non-Mac computers is what drove me to Android. That and, frankly, Apple's overall attitude towards what I am allowed to do on my own phone. Android doesn't really seem to care. As
@mi7chy pointed out, Android gives you torrent clients, emulators, and even terminal access. Google play will let competitors to its own services on without batting on eyelash. The recent iOS/xCloud/Stadia controversy is the most recent example.
As far as the operating systems themselves, I'd say they are about even for me. I find my Samsung Note has a lot more options. I can go on Youtube and watch videos of features on Samsung phones and find all kinds of things I never knew existed. But I do like the simplicity of iPhone as well. What it does, it does well and the interface seems less cluttered. How to do things seems much more straight forward on iPhone. But I guess that is partially due to the fact it limits what you *can* do.
