I don't hate the iPhone, I'm actually jealous of the 11 Pro Max in the battery and design department. Apple creates amazing hardware, no question. Huge battery, and thicker phone, thank you. A+ display. Super fast fluid OS. It's just iOS that irks me, I'm too used to stock Android all these years, I find iOS very uncomfortable and jarring for me, plus I have zero other Apple products, no iWatch, no iPad, no MacBook, nothing Apple in my house, so the whole ecosystem is meaningless to me. I'm not against those products, they look great, just not interested in having them. I don't wear watches, and not a tablet fan, and prefer Intel Windows laptops.
I really like the OnePlus 7 Pro as well, but the curved edge screen is a turn off.
