Simple scrolling in Chrome. If I drag my finger down, iOS responds faster and starts scrolling quicker. There is a longer delay for my Nexus 5 to start scrolling. It is minimal, but it is there. This isn't just in Chrome, it happens in various other parts around the OS.
And BTW, I actually bought an iPhone 5s only to sell it and later get a Nexus 5. I'm not a hater or a fanboy, despite the stupid username that I thought I liked at the time. I just try and be unbias and look objectively. I love my Nexus 5. Its awesome. But lets not pretend Google can do no wrong.
The fact is, iOS respond to touch input quicker than my Nexus 5.
A longer delay between touch input and visuals is not subjective. Sorry.
I am in no way a google fanboy, but Kitkat and the N5 pretty much eliminated any lag android had. On the other hand iOS 7 did iOS no favors. When I pull down to do a search. It hangs for a split second before it pulls all the down. When I am at my 3 screen and click the home button to go back to the home screen. It hangs for just a split second.
As for android I agree there is still some Chrome lag. That is the only place I see it anymore on android. That is why I say they are about even. One place android is smoother. In others iOS is smoother. Gone are the days of iOS ruling this.
