iOS is superior. here are some observations everyone can make. load the game super Mario run, it runs at double the frame rate on iOS. the fps is smooth as butter. android ie galaxy s7 edge it skips, takes multiple times more to load and move from screen to screen, appears to operate at half fps, has lower resolution and blocker look, etc.
iOS main issue is lack of rootability and restrictions on software design placed by apple. for example there are no ability to record phone calls on iOS as android allows. iOS also does not permit developers to include advanced settings tweaks or desktop browser user agent on the browser. android allows both so you can browse desktop sites on android but not iOS.
iOS is not feel friendly or power user friendly as a result so I cannot use it but I admire it's performance. I read years ago the apps being native code use about 10 times less CPU instructions, permitting them to run faster and use less battery, which is why a dual core iPhone outperforms a quad core Android anyday. Android is hog tied by the inefficient implementation of Java which performs worse than any platform I have ever seen, and they use more aggressive power saving features to try to compensate which kills performance.
I am typing this on my galaxy s7 edge now in opera and the bitch is lagging around taking seconds for characters to appear like usual. if I try to switch apps to Google maps the bitch will take 20 seconds or more most likely lagging about. if I switch to Facebook the app scroll is laggy and low frame rate. mother fuck. I go up to the Starbucks counter to order and it takes 30 seconds to get the Starbucks app to stop lagging and finally display and become responsive delaying my order. same issue whipping out the mcdonalds app.
Google fucked up bitch time with androids lame ass design to cause all these issues. the lag is making me want to kill. no joke.
