I currently own both Android and iOS devices, and have used both for years.
I think the single "Omni-Pull Down" from the top works way cleaner than the now 3 seperate pull from side of screen actions. I actually find pulling up from the bottom difficult and frustrating.
Swipe to dismiss, tap to open makes so much more intuitive sense than swipe to open.
Text editing / selection does what I expect way more often.
Android doesn't bug you about Wifi access points by default.
This one is controversial, but I think a visible always available back button is a huge accessibility win even if it's sometimes inconsistant in behaviour.
Also, the Google Assistant at this point is probably 10 times more accurate and understanding than Siri. I have a pretty standard midwestern accent and Siri understands almost nothing I say to a pathetic degree. I use Google Assistant to do probably about half of the quick things I want to do on my phone like set alarms and such. I don't trust Siri to do anything.
A lot of things of course are worse just because they vary between manufacturers and even individual phones.
The fact that many OS components are replaceable is a double edge sword. My dad for instance somehow installed a dialer that made him dismiss an advertisement before he could answer his phone. He had no idea how to get rid of it and assumed he had broke his phone.
