I don't agree at all. My Note 2 is as smooth as, if not smoother, than my iPhone or iPad (when they are first rebooted). Plus, my iPhone 4S and iPad 3 lag plenty of times. Not indiscernible lags: noticeable. Heck the Huffington Post app on my iPad crashes every single day (right after slowing to a crawl).
Even moving around home screens on my Note 2 is smoother than on my iPhone/iPad. This is with many more icons per screen, a 3D transition between screens, a weather widget on the main page, and live wallpaper. Super fast.
As for vertical scrolling.... Note 2 seems to go faster and I can move further in one swipe. I find myself doing less "flicking" like I do on iOS.
But really this is all silly to be debating: they are both "smooth enough" as to it not be an issue. If Android did not get to this point--and they have--there is zero chance I would be using it.

I agree it's a silly debate - each person can come up with some anecdotal evidence that says "My iPhone crashes 78 times a day and I've never had my Note 2 crash".....the REALITY is....

iOS 6 = 1.15% app crashes
JB 4.2 = 1.5% app crashes
In the end, neither the smoothness, nor the crashing apps are what cause me to prefer iOS. Both OSes are mature to the point that app crashes will happen about as minimally as they can and the difference in smoothness - unless put side-by-side - is unnoticeable.
