My experience with Android has been one of declining "helpfulness" and usability in general. I stuck with Android for a long time, (Nexus One - Pixel 3) but with every release Google made pure Android a little worse, and simultaniously made it just a little bit harder to work around the "new" Ad delivery technologies ("Features"). Google Now, the Google search bar, Hangouts with full SMS integration (those were the days), all lost to the Big-G's quest for Ad revenue.
iOS isn't dramatically better, but it is dramatically more consistent as far as an everyday phone goes. I still keep the Pixel 3 on Fi around, hooked up to my car because Android Auto hasn't been entirely ruined yet and CarPlay leaves a lot to be desired.
I found 90% of my issues with Android were resolved by switching out the launcher. No more unhideable 'home' screen of toxic news and ads, no forced google search bar, and I can make it behave any way I want w.r.t. gestures (or not).
Yes aren't those just features of the launcher? I am using Nova launcher and I don't think I can activate any Google feature with any gesture or button press.
