It would not run worse. The stuttering nature of Android is because of the software architecture decisions that were made early in development. The same is true with iOS. iOS places much higher priority on rendering and handling user input which is why it always appears so smooth.
That theory was debunked by members of the Android team shortly after that G+ post made its way around the internet. It has more to do with the number of drawable contexts and the limitations (still) of how they're handled in mobile processors.
