Interesting. For reasons entirely separate from speed and benchmarks I left Android 18 months or so ago, and bought an iPhone SE knowing it was "last years tech". Despite having had mainly expensive, well specced, Android phones including a flagship or two I found iOS the most responsive, least laggy experience I've ever encountered on a smart phone.
I was actually quite shocked at just how impressed I was on iOS 10 after Android phones that had cost me twice as much and many decades learning every UI and UX experience will disappoint.
I have the opposite experience, but these are just anecdotes. Every YouTube video comparing non-Samsung Android to iOS seems to agree with my experience.
