Does anyone know how they differ in smoothness of animations? Both the system animations, and in app performance. I ordered Air 2 on sale because I really wanted the A8X, which in hope would bring me the smoothest iOS experience. And I thought iOS 9.2 with A8X would bring that. But I saw many people say that 9.2 still stutters in animation on Air 2. How much difference is there in SMOOTHNESS between these two devices? I like the smaller form factor, but I don't like that Mini 4 is only A8. So I went with Air 2, although I don't mind bigger size too much either. Will I regret that I spent more for buying the bigger one with faster professor, because there is very little difference? Or is there definitely noticeable smoothness difference in these two devices? BTW, I'm not talking about which one is faster. I don't care which one loads apps faster. i mean if it's SMOOTHER on Air 2, with much higher frame rates per second. Thanks for your help!
