For Android users as well. I hear more Android users defending their choices than Apple users. You talk about peers, but Apple has about 20% of the mobile OS market, the rest is Android. There are more Android devices. So if anything, you'll "notice" your peers have Androids.
And I dislike usability arguments. Often they're rooted in learned behavior. Pretty much: "This doesn't work like this other thing I've used all my life, therefore it's not as 'user-friendly'".
I found Android devices to be a little more frustrating at first because I was used to other paradigms. I get frustrated with Windows 10 because they've changed where a lot of things are from previous versions. It took me a while to get accustomed to Mac OS X's various paradigms.
I personally prefer the iPhone SE. It's got enough beef under the hood and comes in a form factor I'm physically comfortable with. I find most other high-end iPhones and Galaxy devices to be way too large. I don't need a 13 inch screen on my goddamn phone. Hell, if they could make a modern phone the size of the iPhone 4 (Android or iOS, I don't care), I'd be happy as fuck.
But I know exactly why I chose what I chose and I don't cast aspersions on those who choose differently because I don't need to defend my choice.
