Of note: you can achieve a solid 60fps yet still have latency issues. What instinctively bothers people is not just framerate, but the fact that on iOS†, scrolling (for example) has the content literally glued to your finger due to whatever scheduling trick, whereas the ever so slight latency on Android breaks the illusion as the content plays an uncanny catch up with the fingers. Project Butter made great strides to solve the framerate issue but also enabled triple buffering, which by definition increases latency. It's definitely noticeable even on both my N4 and N5 and absolutely jarring on my 2012 N7. † also available on my Mac right now, even though the finger is on the touchpad instead of the screen, the scrolling response is instantaneous.
