Ok, although you can substitute 'Android' with 'Samsung Galaxy Note' since not all Androids are the same:
1. Stylus: I can take quick, handwritten notes, even on the lock screen of my phone, which save to a file. I get far greater precision when navigating full sites with small text targets (I need this for several web-based work apps)
2. Dedicated back button: This is one of the things that will keep me 'Android' for the forseeable future. It's like moving away from one-button mice for the first time
3. App switcher: The iOS version is similar, except I get a dedicated button for this, and closing multiple apps at once is priceless
3. App tray: I don't have to have my home screens cluttered with
everything. The app tray is there for that. The home screen is dedicated (in my case) to widgets like weather and alarms, and frequesntly used apps all arranged
how I want to arrange them.
4. File system access: I can organise files and content however
I choose to, and
wherever I choose to
5. Expandable storage: My Note5 doen't have it, but other Galaxy devices do. I miss it on mine, but I'm under contract recently or I would've upgraded to the Note7 ASAP.
6. Water resistance: Same as above.
7. USB charger: No need for prprpietary anything. I can connect and charge even from borrowed cables. Given that most people have Android phones this is eas(ier). I actually use a Blackberry charger at work I just happened to find in my cubicle from the previous occupant.
8. Multi-tasking (there, I said it

): Apple added some of it recently, for some devices I think. But I need to be able to have, say, Cisco Jabber and my work email or Chrome page open
and visible at the same time. Been able to do that for YEARS now. Combined with the stylus (given the even smaller targets due to the shared screen), this is priceless
9. Customization: This is the greatest of all. I'm not STUCK with Apple's iOS (or even some Android implementation's) Playskool look. I can install different themes, etc, that really do
personalize the device for me.
In short, for me the Galaxy series in particular is the closest we'll get to having macOS on a mobile device, tablet or otherwise.
Hope that helps.
