Think we are kidding? We aren't, even an iPhone 4S wins over a 6S in responsiveness and fluidity. I was disappointed when I upgraded to it to find out that performance was as good or worse than my 4S. One thing I defiantly don't like is that my 6S only gets about 30fps with everything in iOS vs 4S on iOS 6 at 60.So great it lags and an iPhone 5 on iOS 6 STILL beats the crap out of a 6S in responsiveness and fluidity...wow.
You gotta admit, that's embarrassing...
