I don’t know about others but there are still bugs in iOS 13
In 13.’s latest beta in an iPhone 8+ I still have issues (reported) with the removal of hardware based 3D Touch. To be clear, rearranging apps is still difficult and takes several tries and app switching via 3D Touch on the left edge barely works. Yes, I know almost no one uses this but I do and it was a feature when I bought the phone, a phone Apple still sells. And this is what I dislike, as soon as the phone is “old” they start removing things with the justification of supporting newer phones. The iPhone 8 Plus came out just two years ago. I don’t want to dump it yet, simple.
Note that I am not an Android user and this is in not in any way intended to bash Apple comparing it with others.
