I’ve been down the same rabbit hole you are looking into. I’ve been a long time android user, and I switched to the first gen SE and then switched back to android.

The thing about iphone is that, its more akin to a switch phone. If all you are doing is making calls and browsing some social media its good enough. For everything else you will need an android. For me I can live with an android plus an iphone or an android alone. But never an iphone alone.

The smoothness in the os is great and you dont have to brace yourself during every update if it will make you device laggy like what happens in android.

The built is good but nowadays there are androids that go even beyond.

Multitasking and the files app are a joke. How iphone works is that it freezes the state of the app in place when you exit. This has its benefits and cons. Benefits being better battery life and malware won’t run in the background. Con being that almost anything that involves background processes works like crap. Downloads pause, apps reload etc.

Suppose you want to share a hi res pic you took via whatsapp as a file. First you have to go to photos ans save the file to files app. Then go into files and share that file to whatsapp. Something that can be done in 1 step in android.
