Ok, let me see. Again, this is my experience and my opinion, so some things may not be a problem for you at all, for example:
Testing self-developed games or apps. I develop games. To test them on android I just need to create the APK, pass it to the phone, install and done. I may be wrong, but on Apple it’s not that simple.
File management. Many times I use my phone as a Pendrive, others I want to save my music to listen offline. Of the latter I remember that on my old iPod it was a headache to transfer music from my non-Apple PC to the device, transferring other files was just impossible, and it seems to me that that has not changed in Iphone, but I don’t know for sure, since I don’t handle an iPhone.
Going back. All modern Android phones have three on-screen buttons, the order varies, but in general they are: one to see all open apps and close the ones you don’t need or all of them, one to exit the app completely, and one to go back to the previous tab in an app. The iPhones I have been allowed to handle do not have any of the three buttons, the back button is the one I miss the most.
